I don’t think it’s that big of a problem, assuming no one tries to use it for lane splitting. Just treat it as a very narrow car, as in 1 vehicle per lane, and everything will be fine.

I have a feeling that the vehicles in question from the same supplier, and this could be a case of differential tempering going wrong. One of the technologies making a huge splash in the glass world, is purposefully shrinking the outside of the glass around the inside to make a much stronger product. The stress holds…

Fair enough, but I doubt any of these are destined for high volume production.

I believe the dodge tomahawk did that at well.

Doesn’t look like it can lean well, so cornering speed is likely to be low. It would probably really shine on canyon roads with really poor pavement.

Because motorcycles tend to struggle with traction on the front end more so than the rear (although that’s not universally the case). And because trikes with a single front wheel can trip over their front while braking into a corner, which is really bad.

Its a neat, while not entirely original idea, and the execution here seems better than most. Motorcycles typically suffer from lack of traction on the front end (most sportbikes combine supercar levels of acceleration with average sedan braking distances, and understeer typically results in a crash) but the problem…

That part is a tad complicated. The donut is typically smaller in diameter than a regular tire, so having a small tire with a larger tire means that your differential is having to work overtime, and it will eventually get hot, start breaking down its lubricant, and eat itself to death. So the 50mph/70 mile limit isn’t…

Yeah, no. Donuts are limited to 50mph/70 miles in order to keep the temperature of your differential down (since the tires are off a different size it has to work non stop), not to save the tire itself. With stop every hour or so, you can go much further. Run flats cant go much past 50 miles, stops or no stops. AAA is…

If a vehicle is designed around a spare (of whatever size) the space being robbed tends to be reasonable. But simply throwing a full size rim and tire into a truck that never intended to hold one results in a useless trunk.

There is no use arguing against wife. It just means it will be that much harder to find a vehicle that fits her needs.

Donuts can be pushed much further than runflats.

Oh no, the wife wants a small suv with a third row!

I think we’ve all known someone that used a doughnut for close to a month. I don’t recommend it, and it isn’t a good idea, but there is absolutely no way that a run flat can handle that.

Maybe. The fact that they haven’t spread suggest they have problems of their own.

Ok, so I’m being really charitable to your argument, they last marginally fewer miles, while handle not as well, but good enough, all while being somewhat more expensive, right? That’s not exactly a good selling point.

Absolutely, I thought that was well known.

1. Run flats run for a rather limited range. 50 miles or so. So you pretty much have to drop what you’re doing and head over to get that fixed. Which can be difficult as flats can happen after hours, or on weekends.

It makes all the sense in the world for those technologies to quickly come down to the more affordable cars. There are two components to autonomous and semi autonomous tech: software and hardware. The hardware isn’t particularly expensive, and its costs will come down due to economies of scale. The software is…

With two screens, how long does the battery last?
