The systems automatically slow your car. Sensors and radar play key roles in collision-avoidance systems. Iteris's AutoVue Lane Departure Warning System uses a camera and computer to monitor lane markings while tracking them to your vehicle's speed. The computer then predicts when you're unintentionally drifting into another lane and emits a warning signal to the driver. Viseton has developed a crash-sensing system that deploys air bags faster and more reliably.
Sensors detect both the extent and severity of an impact and inflate air bags accordingly.
Smart Cars aren't just about safety, they are also going to be fun. The smart car will more than likely cost a lot of money to purchase so people may want it but don't stand the chance of purchasing it because of cost. There still remains the possiblity of rage if only part of society is able to drive these sophisticated cars and the rest of society continues to manually drive themselves places Last but not least the large issue, already at hand in America and all across the world is the problem of laziness and obesity. Sure the idea is cool because it's a new concept, but it also is threat to the downfall of society just like every other entertainment device that we use and all the other technology that makes it easy for us to live without exerting any force. Until accident liability laws undergo wholesale tort reform, smart cars won't happen.
