Modify the exhaust on smoky old trucks and buses to blow smoke rings.

This is lovely and would create the motorway passtime of attempting to crawl your car through the smoke rings the truck in front leaves behind.

I like this... I like it a lot. One big benefit is that you can drive through the rings of nasty-smelling smoke you it goes around you, not into your vents. I bun anything that makes foul-smelling smoke avoidable.
