Windshield wipers hitting trim

[Gardner Yeaw]

I was driving in a misty rain this weekend and I noticed that the
faster I went the further the windshield wipers moved towards the
outside. On the highway they begin to slam against the trim below the
windshield. I am sure this is due to the flat front and the air
velocity across the windshield propelling the wiper along the way. It
is clear that this has gone on for a long time because the trim is
well worn. Has anyone made any modifications to prevent the wiper from
hitting the trim? It is a most anoying sound, not to mention pretty
rough on the wiper and trim. I think a shorter wiper blade might help,
but that would limit the visibility.

Suggestions?
