super short answer:
1. Constitution vests power to regular interstate commerce with the Congress
2. Congress has exclusive right to control interstate commerce
3. States may not enact laws that would unduly burden interstate commerce (the negation of the commerce clause)
4. States randomly lowing speed limit on interstate to, let's say, 50mph when all surrounding states are at 70mph.
5. Trucks now have to take 40% longer time to cross the state, or would have to go around the state.
6. State law unduly burdened interstate commerce without a compelling justification
7. State law is unconstitutional.
I thought this is pretty well settled. I could be wrong though.

Any argument there must be based on an interpretation, and suggesting that it is a clear-cut legal issue was misleading. Yay, threaded discourse on the internet.
