'06 Elantra: play in steering wheel with wind gusts

I'm curious if this is normal. I noticed that I've had to compensate for wind sheer quite a bit to keep my car straight. Now, to be fair, this was during the remnants of Ike hitting northeast Ohio and 30-40 mph on the wind gusts on the highway, and yet I saw no-one else shifting from side to side inside their lane. I did curb-hop recently at a fast-food drive-thru (actually a tight turn causing the wheel cover on the from left wheel to be bumped). I was hoping that there might be a little more play in the steering than is considered normal for this car. It doesn't pull to one side or the other but there is a point where you have to turn the wheel back and forth to make up for wind-driven wandering. I sure hope that this is unique to me and correctable with the dealership. If a little play in the wheel is normal, I'll be disappointed, but I'd rather hear that from this Forum, than the shop telling me, it's all in my head.
