I mean that's "Park and Ride" which already exists but the problem is that people, kinda rightfully, hate it. All the downsides of a car with all the downsides of a bus.
The solution, which has done in my city to genuinely smashing success is to nationalize the parking garages meaning government builds them, maintains them, and they're free forever. Dot them around a dense mixed use area and quite literally watch the money pour in. Everything is within grandpa walking distance of at least one garage, they're specced to over capacity so each one is never full, and it provides parking to the workers and apartments.

... do people hate park and rides? Where I'm from (suburbs outside a US city) it's completely standard to park outside the city (in a garage or big lot at a train station) and take the train in. I find it quite comfortable personally.
It sounds like yours is specifically for buses, but I think it's that people generally don't like buses, they're slow and uncomfortable. The park and ride is fine when you can walk from it to a subway/train.
That sounds like a recipe for getting a ton of cars into your city. Think of parking garages as "traffic generators". If you cater to cars you shouldn't be surprised if what you get is more cars. It's literally sending the signal to people that it's fine (and encouraged) to drive cars everywhere. After all, your tax dollars are paying for all that infrastructure
Maybe some people are fully car-pilled, but many people want to live in an area that isn't so car-dependent, it tends to make everything more spread out, noisy, polluted, and congested. It also imposes very large personal costs.
