the white car was behind he bus- not in front of the bus where he couldn’t see what was behind the bus- the white car with the black truck right beside the white car=- how could they not have seen it?
We have all seen plenty of people change lanes without looking — and we’ve had to slam on the brakes or swerve to avoid them hitting us. Happened to me yesterday on I-5 when a guy shot the 12 foot gap between me and the car to my left slightly in front of me. It is, of course, very difficult to turn your head and check your right before moving over (/s).
I’m guessing that’s what happened here.
