Boy.... you and 2J in the same car would be an event to behold :~)
If the car died suddenly in the fastest lane of a big bridge, I think we'd both just keel over dead. ;-)
Honestly, for me, it's still a form of claustrophobia, I think. I don't like being *anywhere* where I don't feel like I can get out, which is why interstates freak me out a little, especially when there's traffic on both sides.
