The pedals gas and break, maybe a steering wheel as well it don't as each time but sometimes yes. But I manged to play a game, it just was asking sometimes.
I was using Sony XZ3 and Firefox browser.
I installed Firefox on my phone, and I can reproduce the problem now. Hopefully I'll have a fix soon.
UPDATE: I've managed to prevent the popup menu and it seems to play a lot better on FF now. There's still another smaller menu that popups up occasionally - I think it's triggered by double-tap - but it's much less frequent and doesn't block the whole screen.
