I have been researching mazdas (CX-5) lately and they do get updates to the info/nav system. I think I read there is a crashing problem in v.51 or something, but its fixed in v.55. Not the same as tesla, but better than others.

Are those updates over the air, or do you need to take it to a dealer to apply them?

They're done over USB. The system will look for specially named firmware files (*.up) and auto-apply.

This forum: http://mazda3revolution.com/forums/2014-mazda-3-skyactiv-aud... has some excellent info, and someone usually posts the new FW files. I've done an upgrade and the hacks myself.

"It gives an amazing user experience, "Hey restart your car and it's now got X and Y". Respect." It's basically Apple's model with iPhone and Macs, except applied to automobiles.

Not sure that this is necessarily Apple-specific

In practice, carriers and manufacturers do not tend to release updates for Android phones other than Nexus once the shinier model has come out a few months later.

One of the major selling points of the iPhone is that it will continue to receive full OS updates for 2+ years.

Continuing software upgrades are pretty Apple-specific in the smartphone market, but it's also just as true of Windows and Linux in the desktop space.

Even better, there's already a sensor to let it know the driver's side door has been opened.. that should give it a head start.

The less shitty car makes use this to start the infotainment system early, BMW and Mercedes comes to mind. But the overall state of infotainment systems is laughably bad, there's a few that are merely ok, most are bad, and some are rage-inducing. (Hello Cadillac!)

Agreed. The 2015 Mazda3 we just bought has a horrible info/nav system that crashes and frequently stops responding. I'm guessing the actual chance of it ever being fixed at 0%. Tesla's get an automatic OTA update that would fix that kind of thing and it wouldn't be something you'd have to 'deal' with for the rest of your ownership of the vehicle.

My friend has a Mazda3 and we hacked on it over the weekend to make the infotainment system a little bit better. Check this out: http://www.mazda3hacks.com/doku.php You can turn off the annoying restrictions, change the ordering of some menus and drastically reduce the time of the starting confirmation dialogue box. All you need is a USB to Ethernet adaptor. Also make sure to disable watchdog or you can get into a re…

What watchdog do you mean? I've ssh'd into my Mazda3 and was planning on doing it again soon, but I don't know what you mean by that.

0-60 times are nice but I want to know what the 60-100 time is. That's what generally used for 1/4 mile estimates. Is there any diagrams of information easily available about the couple style used between the motors and the wheel hubs? I wonder how they're done and what the limit of them is with the amount of torque they put out. In a previous life I used to build a lot of race cars and shearing axle bolts wasn't unc…

This article[1] was posted to Reddit, and included a 1/4 mile time of 10.9s and peak acceleration of 1.1g

Here I am trying to imagine a vehicle with infotainment but without a steering wheel. It raises so many questions! Do you assume that we will purchase self driving cars frequently enough that the infotainment will keep pace? Do you anticipate purchasing a personal train or fighter jet? Do the handlebars on a motorcycle count as a steering wheel?

I'm trying to imagine a personal car without a steering wheel without an infotainment system. Of course such vehicles will have infotainment. I've long been thinking about what sort of content would work best. Short, serialized content released on a weekday schedule would certainly be an opportunity. Perfect watercooler fodder.

I always thought it would be cool to play an on-rails first person shooter where the "rails" matched the road you were travelling at the time.

Nice. Not quite as convenient as Tesla, but it's great that they give you the ability to do it yourself.

More usefully, there's an option to increase the range to 300 miles. That's still only half the range of many stock gasoline cars, though.

You only need enough range to go as far as the next charger, or until your bladder is full, whichever is last. 300 miles is plenty (overkill, really) for long distance travel.

Gas car range is more about how many times per month you need to stop at the gas station in normal use. More range makes that more convenient. With home charging, the convenience of an electric car is better even with less range.

The crap they show in the back of NYC taxis does seem to fit the bill (short 2-3 min videos, changes fairly regularly, though heavily mixed with advertisements). It is crap, but I imagine once there are driverless cars, the format will gather interest from more creative sources.

Why use it for creative purposes when you can use it to show ads? Talk about a captive audience. I'm betting that Google is going so big into driverless cars so they can show you ads on the windshield once it's proven + accepted as safer than human drivers. It might take 20 years, but they're opening up a new advertising channel.

Why do you say the other makers are passive? BMW, Mercedes, Nissan, VW, Ford and Fiat all have fully electric cars. Sure none of them get near the range the Model S does, but they are getting involved in this. A Nissan Leaf offers roughly one third the specs of a Model S, but also at one third the price. Seems like progress to me.

Problem with the Leaf is that a 75 mile range is unusable for most people. A 30 mile commute is pretty common, to and from work and you're almost out. Pick up kids and groceries and you'll probably be stuck on the side of the road somewhere. Forget to charge the car overnight and you're screwed. If we take the base Model S, which has a 230 mile range, 315hp, and 0-60mph in 5.5 seconds, it goes for $70k minus $10k in…

According to Edmunds, the MSRP on the Model S 60 (the base model) is $79,570. The average price paid in my area is $79,570. I don't actually know, but I suspect Tesla does not haggle on price.

The MSRP for the Leaf is $30,585, and average price paid in my area is $25,682.

Edmunds does not account for tax subsidies. I think we can both twiddle the numbers in our favor. So the question is, what are the actual cost of ownership of these cars? I still strongly suspect, the Leaf costs roughly 1/3 of the Tesla and is roughly 1/3 of a car.
