At a 90° I'm assuming you're approaching them super slow and then turning really hard and slamming your foot down? Don't slam the foot down, instead aggressively increase the throttle, then back off slightly, and then feather the throttle from there. Don't expect to be looking straight down the road out of your side window though. The car just isn't designed for it.
