| Nov 24, 2020 at 8:43 | comment | added | Roger V. | @Will the car is also driving away from the drops that would otherwise hit it. If we neglect the shape of the car, assuming it just a flat rectangle, then it is always the same surface exposed to the same density of rain drops, just falling at a different angle. This is obviously a non-relativistic analysis. | |

| Nov 24, 2020 at 8:13 | comment | added | Will | @Vadim well the car is driiving into rain that would not otherwise hit it if it were standing still so it is being hit by more drops per second than if it were still from what I understand. | |
| Nov 24, 2020 at 8:13 | comment | added | Philip | Check out Sanjoy Mahajan's The Art of Insight in Science and Engineering (Chapter 3) for a beautiful analysis of the rain problem. That being said, angles do strange things when you take Special Relativity into account, and the number of photons per unit area might be different. (I'm not completely sure about this, but see for example this paper.) | |
