Because it's not consistent physics wise. also the racing titles you've named are hardly competitive racing titles. actual tournament based racing in real racing games have non contact on by default. There is more to racing than simply going through the gates. The fact that you think bumping into others adds so much depth is pretty laughable. I hate contact racing. but at least in other race like titles their physics and mechanics are consistent. compared to SRL where everyone is always a second in front of or behind someone information wise which means people can look like they are bumping you on your screen even though on theirs they aren't close to you. or the fact that you can miss gates you've completely gone through or that connection actually can impact placement and the map itself. so yeah. if SRL was more consistent and not so broken due to their terrible connection algorithm you might have a point.
