Many of your points are about sections being missed out or places being too close to each other - remember that the game's scale is in 1:19 so 19 real life kilometres has to be squashed down into the space of 1 kilometre, which means you have to loose over 90% of the real life distance in order to fit it in game. That's why places are missing, or too close together.
As for, your complaints about the buildings all being 'totally incorrect' - consider that almost all of the assets we use are not creates specifically for one area, with the manpower we have it is not sustainable to create loads of custom buildings and assets for every single city on the map, dedicated modelers are extremely rare to come by, especially for a hobby project like this - so because of that, most of the buildings will be generic buildings that look similar to its real life counterpart.
Looking at google street view, a lot of the places you call totally wrong actually look pretty similar when compare to google maps, take 28:54 in you video for example, which is 'totally wrong' and compare it to
Google street view, I would say it's accurate, even down to the benches and playground.
Lots of the roads in your video were built back in 2016, since then mapping standards have changed
a lot, mapping techniques and standards have improved dramatically, newer areas of the map are likely to be closer to real life. As much as it would be great to rebuild it to today's standards, it's down to having someone that wants to actually spend the hours doing it, so if you want to improve it, by all means go out and do so.
