Beltway 8, The Westpark Tollway, The North Dallas Tollway, and the George Bush Turnpike are all packed every rush hour. Texas seems to be packed with these nobodies, and 400,000 more are added EVERY YEAR (most not from Mexico, in case anyone wants to throw out that red herring, only Florida has more persons from other states moving to it.)
Beltway 8 is only packed because of all the accidents at the toll booths. If they were packed, there wouldn't be much point to the toll, one of its main purposes is to keep people off the road to ease congestion.
