Highway Safety Warning System
The idea is to put a warning system onto cars to warn others behind of a potential accident or bad road conditions ahead.
The basic idea is to have a set of high intensity flashers integrated on the roofs of cars which are connected to the cars ABS (Antilock Braking System). These lights flash repeatedly when ABS comes into play, warning cars up to a few miles behind.
The idea can be further developed by the ABS sending an FM warning or a Mobile alert to cars within a 2-3 mile radius of a possible accident or icey/slippery conditions in the direction concerned (lets say the car sending out the warning is travelling North).
The ABS can determine the type of braking (normal but heavy braking, braking due to ice, snow, sand, oil etc) and send the appropriate warning.
Cars moving in the opposite direction would also recieve the warning but the direction would help them figure out if its applicable to them or not. This signal could also alert the emergency services and end up saving a lot of lives.
Reward: A car with this feature would be fantastic.
