Car-top cargo boxes

[Thomas Erickson]

Well, clearly extra caution would be in order in parking garages and the like, but I think things would be perfectly safe in a nice water tight hard shell cargo box. I mean, people put expensive road racing bikes, kayaks and the like up there all the time. With just a soft case I can see there being some danger of stray tree branches or something though. Clearly the taller the vehicle the more risk.
