Do any of you Tig owners experience excessive wind buffeting with just the drivers window down?

After picking up our Tig today it was so bad our kids in the back were complaining that it was hurting their ears....I have never experienced this before with just the one window open and i can see this as being an issue as i drive the majority of the time with the drivers window down like this.

I have already emailed the dealer with my concerns as this doesn't seem normal to me.
