It only makes sense to sprawl like in Houston if you never mind spending 3-4 hours commuting to work and back. Or if you can't afford anything better. Ask well-paid people who keep renting apartments in Manhattan, or in downtown SF, to say nothing of Tokyo or Seoul.

> It only makes sense to sprawl like in Houston if you never mind spending 3-4 hours commuting to work and back. Much easier to do with self driving cars though. Remember the promise? “Take a nap in your car and arrive at your destination” or “be productive on your commute”.

I live well out of Boston/Cambridge. These days, I rarely drive in. (Mostly for flights or the occasional theater). I would absolutely go in more if someone/something were driving me for a reasonable cost. I'm actually fairly convenient to commuter rail but doesn't really work except for commuting during the day which I very rarely do.

Not really. Get in a car and you can be at all. For many in the city walking it is about as long to get to those things - the distance is less, but the time is similar and time is what counts.(which isn't very many!) the city is the food desert - there are bars and restaurants, but zero grocery stories. If you want to cook a meal you have to get to the suburbs to buy the supplies.

i take it you are not from the old world? Only in north america will you find dense cities without small, normal grocery stores. These are incredibly common in all of the old world.

True. One other people you find in cities in the old world is people who are not in that weird place between college and kids where they can afford to eat out all the time and alcohol hasn't started catching up to their health

Don't many automakers outsource level 2 driving aids these days? Typically someone like Mobileye?

Level 2 is simpler and more mature, so it should be easier to specify, package and integrate. It can follow the traditional OEM outsourcing route, where OEM has high-level models and gets suppliers to implement the details. e.g. I can find public information that Subaru use Veoneer cameras, Xilinx chipsets, but defines their own algorithms. I would speculate they have an outsourced company convert algorithms to FPGA…

Aside from Mercedes-Benz, level 2 is the best we have, though?

Edit: Re-reading your post, you were talking about the future. You make good points; I will be interested to see how it plays out. Probably as long as the technology remains radar and cameras, it will continue to be easily outsourced.

Less mass will yield longer range. I know you're referring to the battery accounting for a large percentage of the weight, but a smaller vehicle will get the same range with a smaller battery, and the weight savings compound. If the vehicle weighs less, then all the components supporting that weight can weigh less as well. Unsprung mass can be reduced significantly. Acceleration, braking, handling, and top speed all…

Interesting, yeah, my instinct is that the sensor weight delta would be negligible but perhaps not.

Fair enough, I guess I'm speaking too generally.

Agreed, it seems inevitable that autonomy and insurance are going to be bundled. 1. Courts are finding Tesla partially liable for collisions, so they've already got some of the downsides of insurance (aka the payout) without the upside (the premium). 2. Waymo data shows a significant injury reduction rate. If it's true and not manipulated data, it's natural for the car companies to want to capture some of this upside…

I would pay so much for my own SUV to self-drive as well as Waymo. Keyword: my own SUV. Not a rental. With the possibility for me to take over and drive it myself if service fails or if I want to do so. The significant unlock is that I get to haul gear, packages, family. I don't need to keep it clean. The muddy dogs, the hiking trip, the week-long road trip. If my car could drive me, I'd do way more road trips and sk…

I think this is the plot of Kamakiriad.

Houston has these, parking requirements, etc. I would argue if anything that mandatory parking requirements have a larger impact than zoning. Parking lots themselves push things farther apart and make not driving unpleasant.

I agree with you but I don't believe the marketplace does. If you get rid of parking requirements in Houston I doubt you'd see a significantly different development pattern because ultimately people there actually do need to park their cars.

If you remove parking requirements then the marketplace can discover the right amount of parking. Parking minimums keep the amount of parking artificially high.

Bundling a real product with a financial institution is a time tested strategy. Airlines with their credit cards are basically banks that happen to fly planes. Starbucks' mobile app is a bank that happens to sell coffee. Auto companies have long had financing arms; if anything, providing insurance on top of a lease is the natural extension of that.

Auto companies, yes. As I understand it, airline credit cards are mostly just co-branded cards with existing banks like Chase.

Frequent flyer programs are basically banks if you consider miles/points are currency.

Agree. But nobody is going to walk or ride in Calgary or Dallas no matter how many lanes you take away. Too much sprawl, too severe weather. There are hundreds of cities like that sadly.

Never heard of DART I guess

obviously there are still TONS of cars. Just look at the highway infrastructure and traffic.

That's different from the credit cards themselves--given the points degrade in value. (And which I should really start to use more.)

Probably a big chunk of these tried ACC a few times, found that ACC sucks unless you're on perfectly clean empty highway, and said "screw it I'll drive it myself".

I've played with it a little bit. Seems useful in principle. But a lot of roads I tend to be on--even highways--have a fair bit of traffic and speed limits that change on a pretty regular basis. Hasn't been as useful as I expected it to be.

It's mostly fine but it has no idea of proper positioning on road. It always puts the car in other cars' blind zones, near to trucks etc.
