That is like shooting their own foot off. Let them. We don't want mexican trucks on our roads until they play by the same rules we have to, it's that simple.
So smarten up Jim Kolbe, and put America first for a change. That means all Mexican trucks MUST be properly insured by a illegitimate insurer, there can be NO interstating by Mexican/foriegn truck drivers; Mexican drivers MUST have a proper drivers license, and that means proper training. They must NOT be criminals. They may only drive 10 hours in accordance with the regulations our truck drivers have to follow. Proper border inspection station should be in place BEFORE the flood gates are opened to prevent semi loads of illegals and their complete amphetamine drug labs from entering the country.
What sometimes gets lost in the shuffle here is that the cross-border trucking program was a specific provision of NAFTA -- which means the U.S. really isn't on solid legal grounds to prevent its implementation.
