Me too - my car has 180 BHP, yet when I drive carefully my record is 960 km
on a single 50 litre tank! To me that is just amazing, a car I had that was
20 years older had only 60 BHP and could do only 400 km on a tank (probably
a bit smaller tank as well though).

I think the biggest improvement is that today, even if you haven't used your
car for 2 weeks and it's -15 degrees outside, you can turn the key and the
engine will fire up perfectly within a second and then idle smoothly. My
dad had a car (actually he still has it) that has no choke at all, not even
a manual one, starting that is a PITA unless you are very good friends with
the accelerator pedal - and it won't idle at all until warmed up fully, so
you need some tricks with your feet when in traffic to stop it stalling!

I wonder how long the "pulse" of radar would need to be - the engine could
charge up a big capacitor to discharge in a roof mounted dish - hmm maybe
not that sounds a bit too much James Bond :-)
