I've considered it, but my commute to work is 17 miles each way. And over half of that is on a Miami Expressway called the "palmetto" which tranlates into: Very Scary Road Where People Die. (or VSRWPD for short)

And When I crunched the numbers it just didn't add up. I would wind up spending at least 5k on a "scooter" that could keep me at interstate speed, add in the insurance cost and I would be better off just driving the ol' jeep every day ( and it's paid for )
