woooo havent wrote on this forum for awhile.

anyways, as i was driving today...i was in the fast lane doing about 80mph when all of a sudden my car jerked to the left like i lost control for about a second. i thought it was the wind or a speeding car or truck next to me...but i was all alone really on the highway and the trees weren't even moving. well a little bit later it happened again. it just jerked to the left suddenly where i had to grab the wheel tight to make sure that i didnt go off the road. (after the first jerk i slowed down to about 65mph and then the jerk happened again) what could this be? it was a little scary...didnt happen again after that, just want to get some opinions. thanks!
