This was a very good discussion of why vehicles get hot. I do have to point out that light does not "slow down." It loses energy, but the speed of light is a constant in any given medium. When it loses energy, UV becomes visible light, and visible light becomes infrared. Also, while it is true that after several hours in the sun a tinted vehicle will be the same temp inside as an untinted one (because the heat lost by conductance back to the outside is balancing the heat gain from the sun), it is also true that the tinted vehicle will take longer to reach this balance. In other words, the inside will get hot more slowly.
