a misguided attempt to discredit a person for their choices.

Low-end printers are way under 2k by now! A kit for a small Printrbot is $350, and an assembled metal one from the same company is $600. RepRap kits are pretty cheap, too.

Honestly, I am not the guy to ask. I generally do simple, low precision, one-offs. I've made things like gaskets, sensors "potted" in urethane, bellows using lost wax, fan stand-offs, etc. Generally, I make the ABS molds in two halves with an inlet port and outlet port. I use metal dowel pins for alignment. I…

I actually do print injection molds for elastomer parts like urethane or silicone. It works pretty well, but takes experience to design the molds properly.

Eventually most specialized things can become one-offs with 3D printing. For example, rocket engines can be tailor-made for each launch (if the satellite being launched is heavier, the engine can be slightly beefed up). Race car parts can be made for each individual racetrack (shorter or longer suspension arms).…

One of the neatest features of 3d printers is the ability to produce shapes that would be impossible to make otherwise. Specifically: sealed hollows or oddly-shaped interior areas. Think of an engine block: all the interior oil and water channels need to be either machined out or cast in place, which puts…

I've always felt (and have said) that the notion of personal 3D printing as the primary source of your personal cruft never made a great deal of sense- which didn't mean that it wasn't fascinating and that I don't make good personal use of it. Your own 2D printer probably isn't even the majority source of paper…

Yes. I wouldn't have thought the insight was ... an insight.
3D printing for industrial applications has always seemed to be at the forefront of the concept.
I may be influenced by the fact that my closest contact with 3D printing is in the space/aerospace context.

It probably wouldn't get you very far. Even on a Model S, the best they could probably fit is about 150-200 watts, which would get you about 1-2 miles in an hour.

That has to be the exit from a Jeep dealership...

No, but I can say needlessly complicated and generally stupid.

The only reason I say "if it works," is because the Combo Wheels system hasn't been tested extensively yet, and, as Houston's KHOU points out, the electronic system hasn't yet been proven to work against weather or flooding. So there's that.

I have a better idea.

A solution looking for a problem

It takes 2 hours to charge at 240V for 1 hour of driving at 60 mph. So, 8 hours a day driving, 16 hours charging, 480 miles/day; 175,200 miles/year; 1,401,600 miles/8 years.

Jalopnik should do a piece on "What can you buy in America for Caterham money?"

That would be the most useless awesome ever.

It tells me that they put "Driver Error" when it may factually be "Equipment Failure/Error" and essentially they are right, because the driver should be driving a safe to operate motor vehicle.

How unsafe is it, actually? Can you back that up? How many accidents are caused by lowered cars with excessive negative camber and stretched tires? I've simply never seen a single accident caused by one of these now-illegal cars, and I assume that's due to the fact that the owners simply care more about their…

We don't actually know, and that's why I'm not drawing any conclusions in that regard. I'm just noting a discrepancy in the demographics of those killed versus the general population, and how it doesn't really jibe with completely indiscriminate killing. You bring up excellent points.
