Here in Ohio, the vision test has been on the books for decade's. The reaction/cognitive test or drivers with instructors over 87, no. Not a bad idea I guess. Real problem I've run into isn't old drivers so much. People on their cell phone is what pi**es my off. Twice in the last 2 years, not this year-YET- had to throw the Sporty into a hell of a slide because some brat, couldn't put the phone down and rolled thru a stop sign. The other was on a 4 lane, I was on the inside lane and they kept swerving right, when we came to a stop light, and his passenger window was down, wont repeat the words I used, but whoever he was talking to, heard me I'm pretty sure. That's against the law here, but never hear of anyone getting cited unless they actually cause an accident.
