Modern cars are evolving beyond machines built mainly around mechanical systems. Electronics, software, wireless connectivity, and remote communication now influence how vehicles operate and interact with drivers.
These advances can make cars more convenient, efficient, and responsive. They can also introduce risks that weren’t as significant in older vehicles. Power failures can affect electronic functions, while connected systems can create cybersecurity and privacy concerns. Technology can also be misused when safeguards aren’t carefully designed.
That doesn’t make innovation inherently unsafe. It means automotive safety now involves more than crash protection and mechanical reliability. Engineers must consider software failures, unauthorized access, emergency use, and human behavior as vehicles become increasingly sophisticated.
The following four technologies show where innovation meets these emerging safety challenges.
1. Electronic Door Handles
Electronic door handles are becoming common in modern vehicles. Flush designs can improve aerodynamics and reduce drag. Electronic releases can also connect with automatic unlocking and other vehicle functions.
The concern becomes more apparent when electronic systems fail. Tesla has faced such problems with its Model Y. The New York Post reported that about 174,000 Model Y vehicles were affected by reports of electronic door handles becoming inoperative. This highlights why newer electronic mechanisms may still need reliable mechanical alternatives during emergencies.
Moreover, some vehicles require occupants to locate separate mechanical releases, which can be difficult to find during an emergency. Consumer Reports notes that these mechanisms vary considerably between vehicles. It recommends making emergency releases intuitive and accessible.
China has also moved toward requiring mechanical door-opening mechanisms in new-energy vehicles. The change reflects concerns about occupants being unable to exit after electrical failures.
The engineering challenge is therefore fairly simple. Electronic systems can provide convenience, but critical escape functions should still have dependable alternatives.
2. Connected Car Features
Modern vehicles can connect with smartphones, cloud services, and manufacturer apps. Drivers can lock doors, check vehicle status, locate their cars, and control climate settings remotely. These features offer convenience, but connectivity can also create opportunities for misuse.
Australia’s eSafety Commissioner has documented cases where connected-car features were allegedly used to monitor movements, remotely lock vehicles, change climate settings, or track a person’s location. Someone with unauthorized access could potentially learn where a person travels, identify regular routines, or interfere with certain vehicle functions.
The concern could also extend to ride-booking services, where passenger assault cases have raised safety questions. Legal cases involving rideshare platforms, including the Uber lawsuit, show why transportation systems must account for deliberate misuse.
According to TorHoerman Law, plaintiffs have also alleged that Uber failed to provide adequate safety measures, driver screening, and responses to earlier complaints.
If criminals learn to weaponize connected technology, they could potentially exploit location data, tracking systems, or vehicle controls to create additional risks for passengers. These cases don’t establish that such technology enabled the alleged assaults, but they reinforce the need for strong safeguards.
3. Over-the-Air Vehicle Updates
Over-the-air (OTA) updates let automakers update vehicle software remotely. They can fix bugs, improve features, and manage systems faster than traditional recalls or dealership visits. This makes them a quick and cost-effective way to maintain increasingly software-driven vehicles.
However, greater connectivity also creates cybersecurity concerns. Gabriel Lim, a senior analyst cited by CNBC, warned that foreign actors could potentially target the controls of connected vehicles. Such attacks could become more concerning as software manages an increasing number of vehicle functions.
A compromised update process could potentially expose vehicle data or introduce unauthorized changes to vehicle systems. Automakers therefore need strong authentication, encrypted communications, secure update servers, and safeguards that verify software before installation.
OTA technology can make vehicles easier to maintain and improve throughout their lifespan. Yet its convenience comes with greater responsibility.
As more vehicle functions become software-controlled, manufacturers need to ensure remote updates remain protected from unauthorized access and manipulation.
4. Digital Keys and Keyless Entry
Digital keys are changing how drivers access vehicles. Smartphones, key cards, proximity sensors, and wireless credentials can replace traditional physical keys. Owners can unlock cars without handling a key and may even share digital access remotely.
While car thefts are declining in the U.S., keyless vehicles remain attractive targets for criminals. The Independent reports that relay attacks account for more than 80% of keyless car thefts in the U.S.
In a relay attack, criminals capture a key fob’s wireless signal and transmit it to the vehicle. One device stays near the car while another is placed near the owner’s key, sometimes inside a home. The vehicle can then mistake the relayed signal for the actual key and unlock or start.
Signal hijacking is another concern. It involves intercepting or manipulating wireless communication between a vehicle and its key or connected device to gain unauthorized access.
Digital systems can also create problems through dead smartphone batteries, wireless failures, or compromised credentials. Strong authentication, encrypted communication, and reliable backup access can reduce these risks.
Replacing a physical key with connected technology doesn’t eliminate security concerns. It changes the threats engineers must anticipate.
FAQs
Are modern car technologies safe?
Modern car technologies can improve safety, convenience, and performance. However, electronic and connected systems can introduce risks involving failures, cybersecurity, privacy, and misuse.
Strong authentication, reliable backup systems, secure software, clear controls, and thoughtful engineering can help manufacturers reduce these risks while maintaining technological benefits.
Can connected cars be hacked?
Connected cars can face cybersecurity risks because they communicate with smartphones, cloud platforms, wireless networks, and other systems. Unauthorized access could potentially expose vehicle data or interfere with connected functions.
Strong authentication, encryption, software security, and regular updates can reduce these risks.
What are over-the-air updates in cars?
Over-the-air updates allow manufacturers to update vehicle software remotely without requiring a dealership visit. They can fix bugs, improve features, and maintain vehicle systems more efficiently.
However, manufacturers must secure the update process because compromised software could create cybersecurity and safety risks.

Modern vehicle technologies can improve convenience, efficiency, security, and everyday driving. Their benefits, however, come with new considerations for automotive design.
As vehicles rely more heavily on electronics and connectivity, engineers must account for power failures, cyber threats, privacy concerns, misuse, and unexpected human behavior.
These challenges don’t mean manufacturers should abandon technological advances. Instead, they highlight the need for stronger safeguards and more thoughtful design.
Reliable backups, secure connections, clear controls, and accessible emergency systems can help address many of these concerns. The goal isn’t simply to make vehicles smarter.
It is to ensure that new technologies remain safe and dependable when conditions change or systems fail. In the end, better automotive innovation should combine greater capability with equally strong safety protections.
