Get used to it, you aren't mistaken!

Looks like 3?

I certainly don't like diesel fumes, Vanagon or anything else.

May be.

Even worse, people just expect that you are slow and accelerate slowly.  In 
my Vanagon I have a much greater frequency of drivers passing me and slowing 
down in front of me, sometimes several times in a single encounter, than in 
other vehicles I drive.  Often this occurs when I am driving just as fast as 
any other car on the road.  I have a steep hill I drive just about every 
day. I can hold 50 in 3rd gear (just about the typical ambient speed).  I 
often see some Honda driver in the mirror with an "Oh no, that big lumbering 
slow thing got in front of me, now I'm gonna have to wait" reaction.  It's 
fun to steadily pull away from them on the hill.
