If you can, carry it inside your car. I was just involved in an auto collision where my car was rear-ended.
Guess what was in the back of my car?
Yep, my C60. I had just picked it up from the shop and was on my way to meeting my wife for dinner. I was stopped in traffic and BAM!
An inattentive driver, looking down at the cellphone was enough to put a major damper on what had been a previously great day.
Fortunately the bike can be repaired. The Thule T2 is toast, however.
insurance will cover it.
Moral of the story: if you can carry your bike inside your vehicle do it and save yourself a great deal of aggravation.
