SE is expressed in a percentage or vertical distance drop per foot (or meter). An 8% SE represents a rate of slope equivalent to 0.08 feet (meter) drop per foot (meter) travelled.

This simulated animation of a vehicle traveling on a properly-superelevated roadway from the Michigan Tech will explain perfectly about the highway superelevation.
Without Superelevation or enough Superelevation the bend or curve will push the vehicle traveling at high speed out off the curve and the driver will normally respond to the vehicle slipping off sideways and leaving the road by turning back the steering wheel to the left.
And that correcting action always overcompensates and the result often is the car overturning on the driver side or even rolling and killing the driver like in the case of Dr. Hideki Hasegawa.
