Because of air circulation and pressure differences in and outside the
vehicle you often get exhaust fumes entering the cabin of a car with a
window open when driving or even when e.g. a boot seal is not 100%.
Modern cars probably are less affected because of a better streamline.
Elongating the tail pipes and/or bend down tips may work but is not a
sure success.
