We already get a car allowance, so it's not likely to go up anytime soon. Of course we are also in cost-cutting mode.
Somehow that dovetails with what is going on, so in the past couple of years my employer has picked up 75% of my ISP, taken over my cell plan, and replaced my pager and cell phone with a Treo 600 to do both functions.
Now, I work from home 2-3 days a week. Of course if I have customer calls, I have to go, but if I'm doing research or e-mail, then I can work from here.
I used to drive 40K miles/year give or take, and with these changes and picking up an on-site assignment two weeks/month, I'm cutting out 12-15K miles/year.
So it the same effect. My boss is really cool about the whole work from home thing, so he shows support and concern in a way that works for all of us.
