“Without changes to those regulations, it may be years before the promise of today’s technology can be realised and thousands of preventable deaths that could have been avoided will happen,” said Mike Abelson, vice president of global strategy at GM, in written testimony released Feb 13. “It is imperative that manufacturers have the ability to test these vehicles in greater numbers.”
Under current law, the US Transportation Department can exempt up to 2,500 vehicles in a 12-month period from National Highway Traffic Safety Administration (NHTSA) vehicle rules.
