We're guessing this was an express route.
While a street flood like this would stop most normal busses, it's little more than an annoyance for the 62. Luckily this flood doesn't seem like a real natural disaster, but more of an annoying road hazard that got the best of the woman in the car.
Unfortunately her vehicle doesn't seem to have the same flood averting capabilities.
In fact, the bus driver is so dedicated to passing the flood that he doesn't even flinch when it looks like he's going to hit her.
Why get stuck in traffic (in what appears to be Eastern Europe) when you can cut your own path.
