Laurence mentions Houston’s asinine new “Move It or Lose It” law, which requires motorists to move vehicles from the shoulder within six minutes (!) or the city will have them towed and impounded.  It’s simply silly to think that anyone can move a disabled vehicle from the shoulder in six minutes if there is any kind of problem at all.  While the professional NASCAR mechanic in the article can change a flat in three minutes, most people don’t have that level of skill. 

Further, Fix-a-Flat can’t be used in Z-rated tires or wheels which have tire pressure monitoring systems.  My Avalanche has a TPM system, and the manual is quite explicit about this point (page 5-74), as is the label for Fix-a-Flat.

I suppose I’d better not blow a tire on a Houston freeway, as I expect it would take me longer than six minutes to jack that beast up and change the tire.
