My guess is after the first year they lower it to 50 since there won't be that many people playing it. Fall guys did it after 3 years, it was sad to lose the 60 person levels which are now 40 if your lucky.
To be fair, to me this does not seem that bad an idea. Live service games share a lot of DNA with arcades. That's easiest to see in mobile, where people play many short matches rather than long campaigns.
...frankly that also includes predatory monetization. People forget that games used to be so hard way back when so that they would gobble up kids' quarters.
For better or worse, live service Crazy Taxi seems to me like a faithful conversion of the original idea to the current day gaming landscape.
