Using eyesight laser to counteract tailgating

This one may be a little too big brother to most but in most driving conditions creating a driver that is uneasy is unsafe. By using the onboard laser cruise control functions you can allow a vehicle to never encroach the space deemed tailgating and create a much safer/respectful driving distance. By creating this buffer space drivers would not be permitted to tailgate and would be forced to drive at a much more acceptable distance (automatic braking would engage to create this distance) . The benefits would be less anxiety for all drivers and safer operating distance for stopping in any driving circumstance(snow , rain etc.)
