Its a facto, but I think people also do think it makes more a difference than it does.

One thing I have noticed from using satnav is that even with a mostly motorway journey the difference between driving fast and driving at a more leisurely pace is never more than a minute or two per hour compared to the predicted time.

I knew it from seeing how often I later caught up with someone driving very aggressively, but quantifying it made me realise just how consistent the small difference is.

I'm not sure this is true. In Atlanta, on a very busy two-lane city-street commute into work, I follow traffic laws scrupulously, and have excellent driving skills, but I take every advantage I can that's not illegal or antisocial -- e.g., I always pass people going slower than me, preemptively change lanes to avoid buses and cars I can tell are slow or turning, take small shortcuts that add many more turns to the trip -- which means lots of lane changes, etc. My wife, on the exact same route and time, does not do any of this; she just follows the car in front of her until she arrives. My driving shaves a solid 10+ minutes off of her 40-minute commute this way. That's significant (>25%), and adds up to 20 minutes more time at home with my kids, etc.

And fwiw, I abhor illegal and antisocial driving and wish there were much more enforcement of traffic laws. And where it's a necessary cost, I'd be happy to have a longer commute if we were all safer for it.

I think congestion pricing is probably a net win, and the lesser evil right now, but tolls are so regressive I wish we could do better by making public transport not suck.

> The thrill

I think it's more of the self-deception that they're more important than others and that they're meaningfully getting ahead of others. This is a major issue in American culture where it's not just about doing great, but about doing "better" than others (competitive in areas it's pointless to be competitive about)
