Same here in the US, only major cities have somewhat acceptable public transport and the price of cars is insane. My advice for you, get a cheap used car (most older cars are good for privacy because the computers are lacluster at most.), and do some preventitve maintince to keep it out of the shop.
You can start by looking up your name on major search engines and delete social accounts that are yours, and for the people search websites some of them have opt outs but most are really annoying and don’t comply (in my experience)
Consider using a privacy respecting browser like Firefox with the extension uBlock origin. Keep it to a max of two other extensions because it makes your browser more identifiable.
Consider using open source software over closed source software (just because it’s open source doesn’t mean it’s always safe)
For email I use proton mail and I’ve been very happy with it along with there other stuff.
As some other people have mentioned, self hosting is a good option if you have the time for it, and a spare computer laying around.
When I was younger I was amazed by how easy it was to track people on the early internet. this is when putting a script tag in a comment section to show images in comments was popular but quickly became exploited and faded away. I also became worried about this in my web development class learning how to use JS and saw how easy it was for a bad actor to execute malicious JS on people’s browsers.
You have nothing to hide huh… So you take a shit with the stall door open?
