I just think not being able to make a little mess (that you will clean up (if needed)) outside your home on a street you pay taxes to keep in order is repressed, ignorant of country/town -
If people aren't "fine" about it it's their problem - moaning about a bit of oil or coolant... on a ball of rock travelling (relatively) at millions of miles per hour round (ultimately) a supermassive black hole

, live a little, take a risk!
I have never had a complaint about doing work in the street, drive, carpark, at the lights... I usually have someone pull up with a smoking engine and ask for advice, that's the reaction I get. Or some kid will watch and learn, or at least watch and say COOL!, or some old timer will have a talk, a biker will beep and flash, thumbs up, that sort of thing... repairing your own car was a pretty popular thing from 1965 to about 1990, it's not as popular now but it's still a done thing.
Magazines like "Practical Motorist", "Hobbyist Mechanic" + tons more - there has been and probably always will be a little sub culture of semi-mechanics (and gifted/practical brainy people), It's fun, it saves you money, and sometimes makes you money, and, you can't persuade me to think any different, keeps me safe.
