I don’t think most tailgaters are driving fast for time savings. I think it really just comes down to the feeling that being forced to drive slower than you want to just feels bad, and if you’re emotionally immature or impulsive, you let that feeling impact your driving.

I don’t let it impact my driving, but I can absolutely feel my impatience rising being trapped behind a slower driver. There have even been a couple times where it was persistent enough to start affecting my focus. My solution? I parked somewhere to cool off, which you might note is the opposite of saving time.
