It's a good thing HV batteries grow on trees with a minimal environmental footprint. Tesla really disrupting the industry.

there are so very many things about this that are amazing,

1) the "battery pack" is a sled under the car, so they're basically having to dismantle the entire car to swap it out

2) there are good odds that they have no idea what battery packs are good or not, because if they did they would have caught this in production/QA at least, so non-zero odds on getting a bad replacement pack too

3) given the cost of these things, what are the odds they won't be refurbing recalled packs and pushing them back into the channel? these are the most expensive component of the vehicle after all

from everything I've heard they'll almost certainly gently caress up and constantly put the defective pack on someone else's recalled car or even back on the same car and mark the recall done due to rank incompetence or negligence from the C-suite down

these are defective long-range battery packs so can they just put them in standard-range cars, hide under a pile of coats, and hope everything works out for the best?

a few winters ago my parents' nest thermostat somehow got itself wedged, and we were without heat in -30'C until we could rewire the old analogue one to turn the fuckin furnace back on

and now apparently the engineers of our favourite Designed By Tesla In Fremont™ doesn't seem to accommodate driving conditions that isn't "the southbound 880/237 junction at 72'F"

never trust something designed in california to work outside california

It must have gotten real hosed up, ours had the wifi chip completely zotted but it simply stopped auto-adjusting on a schedule and acted like a normal thermostat until they sent a replacement.

GPS is ancient. It could in principle be achieved with Galileo (EU GPS) or BeiDou (Chinese GPS). Or by combining data from multiple networks (also including GLONASS, Russian GPS which is even worse than GPS). Galileo has accuracy down to 1 cm, but only for paying customers, and BeiDou around 10 cm.

Also, all of those rely on the timing of signals, so the accuracy will be out of whack during bad weather (EM waves travel faster in air than in water or air with water) or cities (EM waves gets blocked and reflected by concrete).

i'm currently researching modern GPS receivers for a dumb project and as far as I can tell that 10cm stuff only works if you're staying perfectly still, once you start moving it shoots up to the usual like, 1-3m

Clearly we need to make our road lanes 10m wide to account for this margin of error

I 100% bet some autopilot evangelist actually tried to make this argument at one point or another

Questionable though when posted to a thread where people talk about spending tenthousands of dollars extra for a "driver car" and then spend a significant amount extra to take as much driver connection and involvement out of it as possible.

Tesla is stranding people all over an entire continent because they cheaped out of putting a 2$ resistive heater into the cooling loop. And perfectly normal and sane fellow owners suggest stealing air bnb blankets to wrap around the battery.

I feel thoroughly entertained.

We've played with Terrastar subscriptions and can get about 20cm with motion with a single receiver and L1/L2. RTK gps can easily get under 10cm with person level movement; this is how surveyors lay out roads and stuff accurately. Still need somewhat expensive L1/L2/L5 antennas tho.

put a good IMU and some there's no technical reason that you can't know where precisely in the lane the car is. I see more and more bulldozers with antenna masts on their buckets so they can be told precisely where to dig/move. This requires either an expensive subscription, expensive hardware, or a stationary base station (or all three) which is not really applicable for a car going 70mph at an arbitrary location.

gps for lanekeeping only really makes sense if you assume that the road layout never temporarily changes

usually when the roads are so covered with salt that you can barely see the lane lines, the lane layout has also changed because the plows often don't bother to clear the entire road so some lanes are partially or completely covered in snow for a while

winter weather introduces all kinds of weird complications for self-driving vehicles. humans can easily reason their way through that stuff, but it confuses the hell out of a computer program which assumes that everything follows set rules

that's a good point. it seems like drivers tend to cut to the insides of curves more often as well.

Don't need a holster if you never stop shooting.

Magnetic signals are never distorted by large hunks of metal continuously accelerating and decelerating within inches of their source, no sirree

Besides likely being horrendously expensive to maintain and easily vandalized, who's giving up their segment of the EM spectrum to car nav?
