When you commute you see a lot of people trying to buzz around the bus. They must be under the impression that the busses are slower or that they just aren’t as dangerous. Busses however are really big and really heavy, which means that it takes a lot of power to get them moving in the first place, and once they go, it takes a while to stop. This may be rude physics, but it seems to me that the mass of a bus and the energy required to get that bus moving would essentially turn a bus into a battering ram.
In the case of this very unlucky Honda Civic, there wasn’t much left. Albeit high speed and other factors may have been involved, but the lesson for the rest of us would be this simple formula:
Car vs. Bus = Pancake
