Sorry to go off topic, but it suddenly occurred to me how many other interesting model names a PC keyboard can yield.

Ford Escape.
Starting the trend they took the key in the upper left corner.
Some racing organization claimed the next row of keys.
French estates are often called Break.
Suzuki has the Alt(o) and the Sh(/w)ift. Honda the Del (Sol).

But then. Who will claim Scroll Lock?
Where is the Nissan PageUp? Smart Alt Graphic? Chevy Control? Toyota End?

Back on topic.
I can see accurately how much fuel I use and how much speed affects that.
It seems that traffic in general moves way too fast.
That Prius, if it abides the speed limit, is not doing anything wrong.
If other drivers choose to ignore the speed limit and drive at a speed where they waste fuel by the bucketful, not anticipating cars up ahead that do move at a more reasonable speed, it is entirely their own fault.

There is a psychology factor too.
If the 'slow' driving car is anything other than a hybrid you would not register it as someone trying to save fuel. Just someone that drives the speed limit, for whatever reason, be it comfort, having the time, following the rules.
Maybe they like their car and are not in a hurry to abandon it at their destination.

But when it is a Prius you automatically assume it is to save fuel. It becomes an issue. And you remember getting held up by a Prius.
That's why it always is a Prius. You forget the rest.

Unless you drive at the speed limit yourself.
I cannot remember getting held up by a Prius in the last year.
I get passed on the motorway by at least 50 Priuses every day.

It all is just a matter of perception.
