speeding?

I was gonna say Dem vs Rep until I noticed the nose length, unless that is just incidental.

Doppler Effect.

AKA red shift.

Doppler Effect.

I love science-even the Bill Nye type.

Doppler shift. Shorter bluer lightwave coming at you. Longer redder lightwaves receding.

Coming towards you, the car is catching up on its own lightwaves, Vc - S, velocity of light (c) minus speed of car, bunching them together into shorter bluer waves. Receding, it is Vc + S, dragging the lightwaves out as the car adds its speed to the wavelength. Mind you, the speed of the light propagation (c) isn't changed, that is a constant, just the wavelength/frequency is affected.

So if the car came at you fast enough, approaching C, it would appear as a motionless thin line and never reach you. It would take almost forever for the car to arrive, but to the passenger, only a few moments would pass then when he got out of the car, you would be an old man.

Which is why it pays to drive very fast and to live on tall mountains. Both make you live longer by slowing down time!

Blue shift/red shift. Doppler effect as someone else said.

That car must be moving really fast.

With my custom built transmission it could do C.

Just be careful not to go over. You might run into yourself from behind.

Like that day I kicked in the after burners in my F18 and hit my own bullets?

Before you get the prize though, you have one more question to answer.
1. If you were traveling in your car at the speed of light and turned your headlights on, would they do anything?
