100mpg isnt too hard with a purpose built vehicle , and this one shows that its doent have to be entirely impractical to use either.
My favorite of all the microcars is the HMV Freeway and ime debating about making a revised version myself with much more modern mechanicals.(either that or a small speedboat).
The HMV Freeway made production in limited amounts in the early 80's , but it was plagued with setbacks rite fromt the start.
Available in 1 or 2 seater in-line formats it was powered by nothing much more than a 15hp lawnmower quality engine , I think similar to what my Bobcat tractor has.
It had a simple tube frame , fiberglass body , and the rest is how you see it.
check with your local DMV for what qualifies as a "hobeist" vehicle, in wisconsin it's a vehicle that is over 20 years old that has been modified past it's manufactured spesifications, been checked by local law enforcment for safty reasons, they then give you a license plate for it that costs 2.5 times the normal amount but never expires, and is perfectly leagle to operate on any public roads, it's title is relabled to note that it's a hobiest vehicle, and I belive it retains the base vehicles VIN.
I wish I was pro-active , a revolutionary , an anarchist forcing change to the opressive regimes we all must live under.- but in reality , Ime a pussy.
It isn't that glamorous. In fact, it really sucks getting teargassed at a peaceful protest. I haven't been to any violent ones (yet), but I imagine that it gets even more painful then. I remember being at the G8 in Georgia in (I think) 2004 and there being pigs everywhere in riot gear ready to kick the **** out of anyone they didn't like even though there were only a few dozen people at the protest. We wouldn't have stood a chance it we tried to stick it to the non-elected authority figures. One person was maced for no reason and dragged off (I guess as an example).
