Aw, sorry to hear about that lady.
You're actually supposed to -speed up- if there's no way to avoid the deer. Speeding up tips the front bumper/hood of your car down and makes it more likely the deer will either be thrown to the side or roll over the car.
Unlike the poor bastards to try to break, end up with the front nose of the car too high up, and get a thrashing, kicking deer through their windshield.
The best of luck to you with the rest of 2009
