You know all those stories about old people "confusing" the gas pedal with the brake and mowing down a huge crowd of people? Well, they're just going to get worse.
I used to be a big fan of mandatory, regular vision testing to retain your driver's license. Now it turns out that it's completely worthless. So, even if you make people take vision tests to prove that they can still drive, you're not keeping unsafe older drivers off the road.
It's an argument for buying more SUVs and driving everywhere. If some crazy 90-year-old driver is going to have a senior moment and ram me, I want to be as protected as possible.
