Can you read any portion of an eye chart? Can you tell a red light from a green one? Can you hit the brake pedal within minute or so of seeing a red light? Yes? Then you may be qualified to drive a great big truck loaded with Honest John missile warheads! This "Driver Training and Testing Device, Portable" can be yours for a Buy It Now of just $31.99, and it seems like a pretty cool- though admittedly useless- thing to have sitting in the garage. I recall using a device something like this one in driver training class in the early 80s; you watched a jittery 16mm movie of blurry kids running out into the 1948 street and stomped the brake pedal more or less at random.
