  • I disagree. If you can’t merge into a lane without taking up someone’s safety zone, then you don’t have enough space to merge. If the car in front of you wrecks, you have eaten up the reaction time of the driver behind you, greatly compounding the damage; especially for you, who gets front and rear ended.

    The rule I was taught is: if the driver behind you has to even touch their brakes, you don’t have enough time/space to merge.

    That isnt how it works. The speed of light is the speed of causality; it doesn’t have anything to do with light. Its just the fastest speed at which things can happen. Light, being massless, happens to travel at that speed.

    In your scenario, the light beam would just be stretched along its length and the 2D interface on the surface of the moon would just “lag behind” from your POV. But it would lag at the speed of light.

    ELI5: If I’m moving away from you at 50 KPH and you’re moving away from me in the opposite direction at 50 KPH then after 1 hour we will be 100 kilometers away from each other even though the speed limit is 75 and neither of us broke it.

    That’s an extreme reduction but gets the general idea across.
