Some cars are so fast they outrun their headlights. I've slammed on the brakes in the dark only to witness my headlights catching up. ;-)

If you're driving your car at the speed of light, and you turn your headlights on, would they do anything?

One of his which I thought was brilliant, was: "People ask me 'How do you feel?'. I ask them, did you ever lean back in a chair, just a little too far, and almost fall over backwards, and catch yourself at the last second? That's how I feel all the time. "

Since you can not divorce speed of travel from passage of time something rather weird would happen.
If you travel at the speed of light time stands still ie from your point of view travelling from A to B would not take any time. Consequently it would appear to you as if you were in both places simultaneously and at every point in between.
Same thing if you were to continue to travel via C,D,E,F and so on all the way to Z.
In other words from your POV you would be omnipresent.
Of course from the POV of any other slower moving observer you would still just wizz around at an enormously high yet finite speed. But time would not stand still for them so when you eventually stop you would not have aged a bit (disregarding time taken for acceleration and deceleration for the moment) while for everybody else some generations will have passed.
Good way to meet your descendants but you could never go back to the point in time you started at.
The relative speed is the key. You could see your lights from inside your speeding car if you could. but those outside would probably not 'see' them, as the frequency of the emitted wave would be vastly higher (to them). Until you passed, then the frequency would doppler to an ultra low one..
If they had the right equipment, they should be able to spot the light with equipment as you pass by.
(such equipment may not yet exist)
Can spacecraft running at 'warp' get a speeding ticket??
I still work on driving well, being aware of what's ahead, being smooth, being patient.
Leaving early, too. ;-)!
I do believe in getting past someone who is driving badly and I will exceed the speed limit to do it.
We have a LOT of two-lane winding and ripply surfaced bitumen 'Highways' down here. Most with renowned black-spots.
The most stupid thing you see is the long queue of cars with no room to slot in half way along. Thank the lord there are now 2-3km long passing lanes every 10 to 20 K's, but you do need decent acceleration to benefit.

I hear you. I used to love to drive fast and get on it.That was back in the days when Radar detectors actually worked but roads are so congested and people drive like idiots all while talking or texting many times.
