I see both sides since I ride (commute) as well as drive sometimes..
In Cheltenham I get plenty of people doing similar to the OP's video and whilst it's 'close' I am OK with it.
The reason I'm OK is that all the stats point to those not being the prominent danger (

The only mention of 'too close' is regarding Large Vehicles (HGVs etc), if you look at what is attributed to most accidents it's mainly people hitting you because you haven't been seen, or have suddenly put yourself in a situation where you aren't expected..
I've had 3 incidents over the last few years
1. Taxi pulling out from a side road who didn't see me (I stopped just before going over his bonnet)
2. Bus passing too close and brushed my backpack (luckily didn't knock me off)
3. Old codger turning left obliviously, turning in so early he actually mounted the inside kerb and he hit me, knocking me off (nothing serious luckily).
As long as the car driver is in control and has seen me then I'm OK to accept he might want to get by quickly without leaving me oodles of room..
Perhaps it's because I also used to commute on a motorbike and would heavily filter, so having cars in close proximity is something I'm used to..
