Safety upgrades available for older cars
The Mobileye 560 is a small camera mounted on the windshield that monitors the road ahead and sends alerts to a small screen or even to your smart phone. It costs $850 plus installation.
Consumer Reports found that Mobileye works well. Drivers get a lane departure warning if they go over the line without signaling or approach the vehicle in front of them too quickly. And the test using a life-sized dummy found that the Mobileye does alert you if you're about to hit a pedestrian when going slower than 31 mph.
It's mounted in the front, so what it's seeing is what's in front of you, which is great. But it can't help you with blind-spot monitoring or a backup camera. Another aftermarket device, the $250 Goshers Blind Spot Detection System, alerts you if someone is approaching you on either side.
Be aware, the Goshers Blind Spot System isn't all that easy to install. It took a Consumer Reports mechanic 4 hours. So it really isn't a job for the average do-it-yourselfer.
Consumer Reports found that both systems worked as advertised. But they are no substitute for using your mirrors, paying attention, and looking over your shoulder when you need to, such as when changing lanes.
