I live just south of that intersection. A lot of misinformation posted by several Terbites. There is indeed a yellow crossing warning, but the 30kph sign is the ramp speed. I don't know how you judged the driver was at "full speed" as I doubt they were moving all that quick, nor do I see how Polaris can judge someone was stoned. Technically you don't have to signal when using that ramp as it's a continuation of the right hand turn the driver was making (their signal may have turned off after executing the turn). How do you know they ignored both signs?
If you look at the street view you will notice no bushes, etc. to block views. The direction that the cyclists came from is not obscured in any way with sight lines of 200+ meters meaning the drive had 5+ seconds to notice the bicycler even if the biker was at full speed going down the slight hill under the bridge.
If you look closely in Street View you will notice there is a little path bypassing the barriers and crosses the street well before the proper crossing point - this could be a big contributing factor IMO - I wonder if the biker crossed the street not at the crossing (can't tell from that poor video).

Regardless the bicycler had the right of way and the driver should have stopped. There is OPP station 100 feet to the right of the intersection.
Now I'm going to say something very politically incorrect and do some of my own guessing: That area is affluent/expensive and a certain culture is buying into the neighbourhood big-time. As a result there is a lot of new-to-Canada inexperienced drivers and there is been a marked increase to accidents and other traffic-type problems in the area. Traffic has really increased and the traffic interchange is an old school design. I get cut-off all the time, people drive through yellow/reds .... it's crazy.
