All kinds of interesting cars in this video describing 'car failures', like the Davis 3-wheeler, the Tucker and some cars I've never heard of...

^^ I watched it hoping to see more of the Velorex Hoba 2 shown for the teaser, but there were no economy models at all. Those Ruxton headlights had a trick reflector that had a focus point at the top where a cigarette could be lit. They gave a decent pattern with a more streamlined shape.

Hope it has air-suspension, otherwise it risks knocking both ends off the car on the first driveway!

I saw it a week ago, but thought it was not a real car.

Hardly any wheel clearance. Imagine what happens if an acorn or a pebble gets stuck in between!

I dunno, look at all the rice rockets and low riders, they get by with ridiculously low clearances. Not pretty but doable.

Looks good. A pity they pulled the plug.

I saw one thing I did not like though. The battery pack is made out of 32 modules each containing 252 cells grouped in 6 banks of 42 parallel cells (but arranged in 10 rows) with top mounted contacts.
This is more or less comparable to the Tesla Model S and X setup, but there each cell has a lead that cats as a fuse. Should the cell fail or get severely out of balance with the other cells in its bank, then it will draw a big current that blows the lead, isolating the defective cell.
The Dyson cells appear to be hard-welded to the copper so no fuses there... A single failing cell could therefore kill the bank or maybe even get overheated and catch fire.

The battery will be problematic, and so would setting up the whole production facility; new design, no car manufacturing experience.
It is a prototype though and the pack is designed to be adaptable to different cells; Dyson could just get batteries elsewhere.
I'd love to see Dyson strike a deal with Tesla for their packs and production technology to build that car for real.

Does this one count? When you've got a big family, but don't want the crappy gas mileage most 3 row SUVs and minivans get...
