The other is shows a real life braking test on a snowy bikeway. Not really icy yet because the snow hasn't been trampled on enough, but there was some ice on it anyway. The big trucks do not have studded tyres so they're pushing the limit a bit by stopping at a steep hill. I'd say they couldn't have fit trough the underpass, so they would been stuck if they couldn't get up. They could have turned left or right but came up straight, and afterwards I was wondering if they turned back or drove through the no entry signs to the pedestrian crossing to get to the street at the very beginning of the video.
Note the mail van, it's a special, expensive vehicle designed for mail delivery ie. right hand drive so the mailman can reach the boxes :-)
Some commenter talked about the aversion to two-phase left turns: having to first cross one street and then wait at another red light certainly is a pain. Even if you don't have dutch intersections, if you have paths on both sides of the street you can cross the street when ever it's best for you and then make the left turn at will.
