Jim you forget who is asking this question.. it would mess up a BMW and that is just unacceptable.

If at first asking the elk to stop smashing your BMW does not work, you should push the panic button inside the car.. Don't have one? You should have gotten a Mercedes.

Drive away..it's why you have insurance..but you know that seeing as you work for you dad and complain about the fat lady enough.

Should the elk continue to pursue after your attempt to out run him at 65+ mph, hopefully you don't become further infuriated by the people doing the speed limit while the elk is still keeping pace and attacking your vehicle, obviously preventing you from eluding the elk.

Then.. I think you could shoot. Just hang out the car window, drive w/ your feet and blast away. I do hope that you aren't carrying a 9mm though, we know that won't stop an enraged elk.. studies have shown.
