A safe distance.

I like my older brother's philosophy on tailgating.

	If you follow at 4 or 5 car links and the guy ahead of you slams
	on brakes or hits something, you're gonna really smack him pretty
	hard.  If you're only a foot or so from his bumper, you distribute
	all your energy into tearing up his car - no impact between you and
	him.

Sounds good anyway.  And makes sense, given the assumption that you're 
gonna make contact.
