You mean perpendicular?
Yeah, it sounds like what I thought. The problem is understeer is very hard to control. You can brake the inside rear wheel, but too much brake will induce oversteer (like pulling the e-brake), so some cars apply brakes to some or all the wheels in order to slow the car down. I think you got into heavy understeer control. Had you been in "sport mode," i.e. brakes only, no engine control, you may have been able to power out of it as well.
