A coal-gas powered taxicab operated by John Lee Automobile Engineers in Keighley, England. The bag atop the vehicle stored sufficient fuel for 15 miles of driving (c. 1920s)

if those engineers could only hook it up to some of todays politicians and fly they around with all their hot air gasses they produce

I believe thats a woman driver. Also that car steers from the left. When did they change to right side steering?
just

Cool photo. What is the bag on top made out of? It would have to be a pretty sturdy material to hold any kind of fuel. It looks like plastic. If so, it would be a hazard.

I believe the engine is using the same concept as Wood Gasification so the bag is effectively holding gas vapor. In 1920 maybe the bag was made from waxed canvas or gelatine-brushed cotton like blimps -- weight is not the issue. I think the pic is an optical illusion -- Looks like Right Hand drive to me. Very cool - Thanks for posting.

Looks like a lot of space between the steering wheel and the window frame.Wouldn't be if it steered on the right. Not much space on the left.

15 whole miles

Left hand drive. Look at the license.
