The Tesla Thread

I think the jury is out on M&S heat pumps ? they were seen as the great white hope(like android automotive app support) - but some of the tesla trials in colder climates show higher consumption, less effective at lower temps (even vw's co2 one) too - is the additional cost ever amortized.

Do any manufacturers currently offer assisted driving that reacts based on traffic light colours - even if FSD eventually will ...
I'm even doubting that the AEB systems are seeing colour of my hi-viz cycle jackets.

I'm fully aware of the difference between a heat pump and a resistive heat source. My point was that comparing two manufacturers thermal management systems is more complex than just stating if it has a heat pump.

Dont think the difference is significant. As said packaging is the benefit but is it at the cost of performance in cold ? Octovalve is just a multi valves heatexchanger . The Tesla one is cnc machined so doesn’t really look like a mass production solution where economies of scale would point to a difference solution

Like Over The Air (OTA) updates - those are common too.
My Polestar gets revised functionality or new features added every couple of months. Car Play is coming in Spring and they have previously improved battery pre-conditioning, one pedal driving, range & consumption and even changed the way the electric windows go up, via software updates. Along with a load of other stuff too.

How often are the updates? I'd imagine it's a differentiator for Tesla (for good and for bad). Check out the frequency https://www.notateslaapp.com/software-updates/

Note not all updates make it to all cars. But 1 a week or so seems normal so far for me.

Er no. What happens if you got a 70% state of charge and stop to get 15% more so you can complete full journey without stopping again. You might only get 90kW from 175kW, fair enough if it was a 7kW charger, but not on an Ultrafast.

Polestar only has 1 car with OTA updates.
In terms of frequency - probably every couple of months but when they come there is a long list of features.
Looks like Tesla release more frequently but with only a couple of additions each time. Also, some are what appears to be software devs updating for updates sake.
 
I'm happy to be corrected, so it's good to know Polestar are committing to regular OTA updates. That should be standard for all cars though, not "bring it in and we'll update it" which has been the way with some manufacturers for years.

Not sure what the point about LIDAR is though. The FSD visualisation in my M3 clearly shows the traffic light colours and the road arrows/stop signs painted on the floor.
 
FSD see's in black and white, the amount of data going up to colour is astronomical and cannot be processed yet (and it's not very useful anyway). It does however see which light is on/off and know regional styles and hence which one is red and which one is green. Each camera is 1280x960@36hz.

We'll I've been trying to decide between a model 3 (sr / lr) or a model y and have ended up ordering a model 3 sr. The amount of miles we do a year was the main factor in our decision.

To be honest, I wasn't planning on ordering one yet, but the website stated November 2022 and I need a new car in September so went for it. My work will let me hang on to it for another couple of months.

Hello Teslas

Looks like I will be able to get a Tesla (well, order one anyway) as a new company benefit pre tax. I believe this is BIK which is 2% on an EV.

Can anyone confirm if that is, for say a 50k or 500/month lease £1000 per year extra tax (50k @ 2%) paid when submitting return?

TIA - never had a BIK car before.

As an owner of a M3P, I agree it lacks character, or possibly a better way to explain is that it requires almost zero mechanical sympathy. Point and go. To the point where it doesn't feel fast anymore, I just wonder why everyone else is so slow.

The question I am stuck with though is if that's really a bad thing.

I don’t know, have you drove other stuff to compare?

Bit lost, Mud & Snow heat pumps? Yes they do work but it’s significant heat demand to warm the battery and cabin on cold regardless.

FSD will start moving and stops based on traffic light colours/ interpretation of colours based on monochrome as I’ve learnt is possible from this thread. I guess experience here might help move you away from thread bare Socrates style one day…

DC penalties? No chance, idles fees once full is sufficient. As we move to the KemPower style power modules with a post array to share the cabinet power it will be less of an issue anyway.

EDIT: this stuff is probably more appropriate for the electric thread again.

the point was - given that tesla have visible light cameras as opposed to lidar - what are the capabilities to robustly recognise red/green lights and help the user brake,
for other manufacturers as well - FSD will need a robust technique.

google shows dc charger billing strategies that would address inefficient use
  1. Bill by time. At a high-use station, the most valuable commodity in play isn’t the electricity – it’s the opportunity to charge. So, billing drivers for time spent at the station directly addresses their use of the charging system. Also, as the charge rate drops, the cost per unit of energy increases. This model also strongly discourages drivers from leaving their cars plugged in after the charge is complete. A minimum charge could be incorporated to cover transaction overhead – for example, $2.50 for the first 10 minutes and $0.25 for each additional minute.
  2. Bill by time escalating. This is perhaps the best model for a busy urban site where many drivers need, for example, 10 minutes of charging to pick up 20 miles of extra range. A billing rate might be $2.50 for the first 10 minutes and $0.50 for each additional minute.

... already some deviation on the thread.
 
LIDAR supplements the current stereo camera as we move to level 3 ADAS; the cameras that currently manage traffic sign recognition, lane keep assist and matrix lights, it’s not one or the other.

You’ve used Google to reference an idea that falls close to simply being common sense- incredible.

BIK is paid on the list price so it's totally unrelated to lease or even purchase price. For example grants don't change the list price But yes, the % is otherwise paid on that in one go when you submit your P11D.

You can find the list price from a quick Google.

My last car was a 370+ bhp tuned 7.5 golf R, so sub 4 seconds. What struck me is how the M3P doesn't require launch control etc. How many ICE cars are 3.2s to 60 without launch or any drama?
Click to expand...
How or why would an electric car implement or need launch control? Almost immediate maximum torque from minimal RPM, no gearbox, just power from the low end to the high end without any gear changes, waiting for turbos to spool, or in-gear power bands to worry about.

Of course the bits you are missing in the electric car help with the sense of occasion, and flood your senses with vibration, noise, even smell, adding to that immersion.

There’s little doubting the M3P is mightily impressive, but it is far more clinical in it’s approach to performance than any ICE car. For some that is a massive turn off.

I can’t wait for my M3P to arrive, but I’m not kidding myself that it’ll beat my previous 2016 S3 saloon or current 440i in all areas, excluding pure performance.
