I was doing multi-modal a few of seasons ago and it worked out great. In my case it was the lack of bike-friendly routes near my workplace that instigated it, i.e. I was riding about half the distance from home to work, and driving the rest; reverse in the afternoon.

The above is all true, but as an automotive engineer I can attest that late model cars (<10 years old or so) have very effective coldstart engine management strategies that minimize pollution during the coldstart and warmup phases. So-called ULEV and SULEV rated vehicles are even better in this respect.
