A car should not ever be driven faster than conditions allow. If the driver cannot see (from rain, snow, darkness, etc.), then they need to slow down. To do otherwise is putting people on the roads at sever risk of injury or death.
a) there are people on the roads inside those metal boxes on wheels, y'know.
b) "shouldn't be there" is not a bianco cheque for "run them over", at least in the civilized world
