If you're cycling, and an officer asks for ID, it's best to give them something OTHER than your driver's license - they usually don't understand that bikes are subtly different from motor vehicles, and if they're going to write you a ticket, you don't want it connected with your drivers license, which is technically your 'motor vehicle operator's license.' Tickets received on your bicycle shouldn't count as points against your driver's license. That'd suck having your car insurance go up because of something you did on your bike!

Yes, they can write you a ticket for speeding, but OTOH, bicycles are not required to have speedometers. So by extension, you aren't required to know how fast you're going. Speed zones might be unenforceable against bikes (check with your lawyer on that one though.)
