Not the worst driver ever, but close

Driving  to work this morning, I came to a crosswalk with a red light, so I stopped.  Most crosswalks here use stop lights that point in two directions along the road being crossed (as opposed to regular stop lights that point in four or more directions).  These lights flash green until a pedestrian presses a button, whereupon they go red for a minute or so.  Drivers must obey these signals exactly as if they were regular stop lights.

I didn’t see a pedestrian, which means they probably already crossed before I got there.  Anyway, when I stopped, there was a car stopped opposite me, in the oncoming lane.  This car was signaling for a right turn.  The crosswalk in question is – like so many others – at an intersection of a minor cross street.  Access to the main road from the cross street is controlled by stop signs.  There has always been some ambiguity regarding whether it’s okay to turn right at a crosswalk that’s currently RED if doing so causes your car to pass through the crosswalk, so I just assumed that the driver wasn’t sure and was waiting for the light to go back to flashing green before turning.

As I waited for the light to go back to flashing green, in the car opposite me, the driver looked up from whatever they had been doing, and without waiting for the light to go green, drove straight through the crosswalk – while still signaling for a right turn.  The car behind them pulled forward and stopped, and its driver and I exchanged a puzzled look.

For those of you playing at home: how many mistakes were made by the first driver opposite me, and what were they?
