I'm glad this thread was started. I'm 25 with Aspergers. I have no balancing issues, however the sirens and flashing bike lights have been an issue. I've had 3 seizures due to certain sirens. I tried my concert earplugs (ones that let me hear everything around me normally) but the wind noise from biking with those in left me deaf. Any suggestions?. Obviously I can't get a drivers license due to a history of seizures (I can't go a whole year without having one), the local buses are noisy and disgusting and I hate cabs. I got excited about roadbiking but I'm getting a little disheartened due to this issue.
