YANBU. Absolutely not. @MaMaD1990
But you won't get much support on here. Even if people have a 4 car drive, many posters on here will say it's ok for them to park on the road, (preferably opposite your drive just for good measure.) Because they can, and because the law says it's allowed.
I agree with @SoupDragon that just because you CAN do something, doesn't mean you SHOULD.
I also agree with @billy1966
It's extremely selfish and what I would call a move that marks you out as a twat.
Anyone who parks on the road when they've got a driveway to park on is an inconsiderate oaf. Just try doing the same to them though. Park YOUR car outside your driveway and on the main road, and you get evil looks.
IME, these are the same individuals who play music loud in their house, who have loud get-togethers in their garden from 3pm til midnight every weekend between May and October, who leave their wheelie bin on the footpath for 3 or 4 days after it's been emptied, and who let their dog shit on public footpaths. The 'I will do what the fuck I want' brigade. We all know people like this, and they're the worst kind of people.
