Re: Did he get a ticket?
And he really must not have paying attention as usually firetrucks with emergency lights on are quite visible from a distance which means he didn't notice other cars moving over to the other lane that is if there were other cars in that lane. I smell a porkie.
Not defending the tesla dolt.
I've been in a couple of crashes (mostly NOT as driver, just FTR), and known others who've been through them. Accurate recollection of events is rather difficult even for the best people. People go through quite a shock - physical and emotional - in accidents, and recalling what you were doing or what was where at the moment things became a serious problem really is very hard.
Especially when you plough into a parked vehicle while looking for that bit of pie you just dropped (nope, never done this, but you should be able to find footage on YT of someone doing just that)
