I haven't watched the video (and dunno if I will because I find him annoying) to know specifically in that case, but personally I've seen more toxicity from the people defending the system, suggesting people are "entitled" and "kids these days don't want to work for anything" and snarky "wow imagine having to unlock things in a video game" type comments. There's also people saying "I don't care about multiplayer, the system is fine" or people who don't even play multiplayer saying people are being whiners and it won't be a big deal.
As has been discussed previously in this thread, this system likely won't do that. You can't force people to learn, and in trying you will probably just annoy/frustrate them. People that suck will still suck, and they will still learn nothing from leveling up their cars, they will just complain about it and take longer to level them up than the people that are learning.
People learn what they want to learn, and while it is logical to assume so, learning and being good isn't tied to seat time, as many games can clearly indicate. In the league I run we have a guy who has been running with the league since FM1, driving everything from beginner cars like Clio Cup and MX5 Cup, up through NASCAR and GTs. He makes the same mistakes, argues with people who give him advice, rejects tunes from knowledgeable players, and after nearly 450 official league race starts, he has yet to get a single podium, even through inverted grids and the dying days of FM7 where car count is down. He isn't the only one either, we have several drivers with 200+ official races and only a podium or 2 thanks to inverted grids,multiclass attrition, or low attendance... and these are people who are serious enough about their racing to find an organized league to race with.
It's not just racing games either, games like GTA have people who are level 500 and can't drive a city block without crashing into a traffic car or can't make it across town without stopping multiple times to open their map. Yesterday I played For Honor with someone who was over 4x my overall level (and I have 500-ish hours into the game) and triple my level with the same character, yet only knew 1 combo (f you count a combo as pushing the same button 3 times in a row) and never dodged or blocked any attacks. I also regularly run into players who are half my level who are noticeably better than I am.
Whether people are good or improve is irrelevant for single player, but multiplayer is where it matters as it impacts others. The skill/safety rating system will likely be a much better motivator for people, as having a rating next to your name labeling you as someone who sucks and is dangerous will probably inspire people more than a car XP bar, and more people will be motivated to get out of the crash-fest low safety rating lobbies. Even if it doesn't motivate anyone at all though, it should at least make it so people who do care can progress up the ratings and get away from the people who don't care.
In a racing game, a skill and safety rating system is a far better progression system than purely grinding anyway... but it's just hard to implement for single player content where you can control AI difficulty and stuff.
