There are some new after market offerings in this space, where you can update your older car with collision avoidance. These systems don’t take over the vehicle or anything like that, but they beep when you get too close to someone, change lanes, etc. I thought about installing these on my kids’ cars, but then I recall having the technology in our Chevy Volt and found it to be a nuisance more than anything. The only thing I did like was the collision warning beep, which did in fact sound a few times. You can get these for a few hundred $ all the way up to $1K, plus installation. Worth it ?
