I hope they both make it.
Regarding the autobahn, yes they have no speed limits, in certain stretches. If the road hits a certain angle there is a speed limit. I have been there and I have driven over 100 mph for good lengths of time.
The difference there is that the road is designed for it, everyone is driving that rate of speed, there are good drivers there, they adhere to the laws of the road, etc.
It is much safer to drive at those speeds there but you can't relate that to driving 100+ in the US where the roads aren't designed for it and no body else is driving at those speeds. Oh, and just forget about the fact the we can't drive by the laws of the road here at 55mph.
