One thing you get on a bike and usually don't get in a car is the scent of where you are. I've noticed recently how many smells I come across in my commute. I don't have particularly sensitive sense of smell so when I can smell something good I tend to enjoy it.
Sure sometimes I have to smell bus exhaust or roadkill but riding past the coastal sage scrub I get reminded by scent of camping as a boy scout. I also get to pass a number of great smelling restaurants. I get the smells of corn tortillas or just the general scent of Mexican or Asian-fusion cooking.
