No. And it would not matter if the void were full of light and you did or did not turn on your headlights. You would not see it. Nothing, no photon or other form of information, from the car 100 feet away could catch up to you and impact on your sense organs. Neither could you receive a radio message transmitted from the other car.
There is an elementary Denkfehler in thin ...[text shortened]... at c cannot send and receive back a reflection from the other vehicle travelling at the same speed.

Einstein's fundamental insight is this: the speed of light does not accumulate, unlike the speed of a bullet. For example, if a bullet exits the muzzle of a gun at 200 mph, and the gun is pointing forwards on a freight train moving at 100 mph, then the total speed of the bullet is 300 mph (minus some air friction, of course). Whereas, if you shine a torch off the front end of a freight train moving at 100 mph, the speed of the light beam is not 100 mph plus c. It is c. Just c. The speed of the freight train does not influence the speed of light. Therefore, if the train is moving at the speed of light already, a light beam shone off the front end of the train will not exceed the speed of the train itself, it'll be 'stuck', as it were, on (or in) the light source itself.

@moonbus saidBUT WHAT HAPPENS IF YOU DO IT IN TOTAL DARKNES WITH A SOLAR POWERED TORCH.

@moonbus saidSpeed of light doesn’t accumulate but a photon fired out of the back of a vehicle moving forward at the speed of light will still exit the rear of the vehicle at the speed of light. It won’t be stationary. Surely?

@divegeester saidI am going to have to strongly disagree with you of course. 🙂

True, Hate to see a grown boy cry. 🙂
Appears he alerted your post, he who never alerts posts. 🙂
I didn't add you quote so even if it gets removed this should stay. 🙂
