I totally feel the resentment everybody's chewing on here, and I know it's hard to choke down the anger, but if you're going to take the high road (and actually do something good for cyclists), how about something like:
"Yeah, we need to get more law-abiding folks like
YOU out on bikes. In places where biking is a normal, average way to get around, people are more likely to follow the rules and less likely to act freaky. Here's my card -- call me if you want someone to show you the good bike routes around town."
or
"You sound like you care a lot about traffic safety. Why don't you become a League Cycling Instructor? Or at least donate some money to your local bike advocacy group to subsidize safe cycling classes?"
or
"Yeah, a big part of the problem is that almost nobody in the US gets a driver's ed class for biking. Can you help us out by pressuring the local school board to make safe traffic cycling part of the high school curriculum?"
or, if you'd rather,
"Yeah, if we're ever going to get really safe roads, like the Netherlands, we'll need to stop paying lip service to bike safety and invest some major cash in safe separated infrastructure. Will you lobby your congressperson?"
In other words, "YOU'RE EITHER PART OF THE PROBLEM OR PART OF THE SOLUTION. HOW 'BOUT HELPING OUT, BUDDY?" But don't say it like that.
