I'm in the process of investigating similar options myself, including polyaspartic.
I'm a bit fickle and cheap, so I keep coming back to marine grade square carpet tiles with a drip tray (just in case). Carpet is warm, cheap, easy to replace square tiles, and I'm told keeps dust away (probably just sits buried in the carpet). Rollers work on it just fine as they are rubber and short pile. Also if I get bored, I can easily change the pattern cheaply and easily.

That said, my set up is a little different to most. I do have a seperate undercover enclosed carport area where I can move the car to, with concrete floor, where I can mess with things that cause fluid spills and the like.

Ps. That terrazzo stuff looks good. But I can see me wanting to change colours or patterns every few years. Same dilemma with polyaspartic.
