The NHTSA is taking public comments on the ATA speed limiter petition . Reading the petition shows statistics were really twisted to give the results ATA wanted . For instance , accident figures for "large trucks " included all trucks over 10,000 lbs. gvw . Rad it yourself http://a257.g.akamaitech.net/7/257/2...007/07-326.htm . Congress had already decided there was no justification for speed limiters . If you sit back and let this pass there is no telling what the ATA will come up with next .
