...Or... maybe you won't be able to let us know how it went!Yes that is a good question. While using it I've actually come to a complete stop, such as at a toll booth, and then accelerated to cruising speed again, all while never touching the brake. It works great. I'm going to test out the front emergency braking by driving at 70 towards a bridge abuttment and not touch the brakes and see if it stops me. I'll let you know how that goes.
