[uk] UltraSonic Sensors removal/TV replacement performance

On a revenue of $59 billion (2021). That’s 0.17%, or the equivalent of someone earning 50k saving ~85 a year.

I really don’t think the conspiracy case that this about cost saving adds up.

Tesla generating this much ill will for such a small revenue saving would be like that person on 50k stopping buying toiletries and deciding to stink all year to save the 85. If their financial results come out and show that they’re in a difficult place maybe I’ll rethink but with the margins they already have I do not see this as a business decision anyone would realistically take.
I know! Ridiculous! There will be rumours next that they want to eliminate stalks to save a similar amount!

Great analogy by the way, about someone stinking all year to save a trivial amount. I recall one of those ludicrous penny pinching CEOs in a California tech company that he bought for >$40bn sacking all the cleaners and refusing to pay for bog roll. Noone in their right mind would do such a thing.
 
I think the thing is that on ICE cars the fuel tanks are big enough that it's merely an extra cost issue from lower mpg vs having to fill up too often. EV's will solve this range issue once they get more dense batteries that even if they are quite out, the real world range will still be plenty. I don't think real-world ranges in the 100 - 200 mile are acceptable unless you want a little city run around. That's a range you might be hitting in some Tesla's for instance in the winter and more so in other brands of EV's. Similarly I don't think 200 - 300 is probably good enough. 300 - 400 is fine, 400 - 500 per charge is probably getting towards average ICE cars at a guess.

They can argue you need to stop and stretch your legs, go to the toilet or grab a bite to eat and charge during those times but going to the toilet, stretching your legs isn't going to take EV charging times. You could grab a sandwich and that ain't gone take as long and your forced to also stop somewhere that does have EV charging. I can get 600 miles out of a tank on my ICE, generally if I fill up at start of the journey there's little I ever do that I'd ever need to fill it up on a trip. Can stop anywhere I want, when I feel I need to stop and not the car.

This will come to EV's I suspect, just going to take a while for the battery tech to get there and be cheap enough also.
The other fault in the ICE analogy is that one could regularly fill it to the brim and use it almost down to empty. For EV that would be horrible for the battery life. Additionally, larger batteries have longer life because you do not need to fully cycle them that often.
Also, ICE are so inefficient that racks, cold/hot, small hills do not affect it as much as they do EV.
So, in practice, EV range is 60-70% of the advertised.

Some excellent points there.

The other issue is if you DO run out of gas at the side of the road, a lift to and from the nearest gas station with a 1 gallon can is all it takes to get you back on the road and get on your way again. Maybe vehicle to load partly resolves that problem? Oh, sorry that's for forward thinking companies.....

Agreed some great points and as you say you are probably running the battery mostly from 80% to 20% so 40% of capacity isn't generally used. Also they tend to keep some of the battery capacity back also because going down to zero isn't great. Honestly think we need some new battery tech soonish to solve a lot of these issues. Lots of issues solved in labs but man does it not take a long time for anything to make it to production.

Some road assistance companies started carrying ~25kWh batteries for fast charging. I think there is a Finish company that makes those. The same idea like the current jerry cans. It gives you enough energy to get to the next charger and because the car is almost zero it does it very quickly.

But now you add in the 2÷ hour delay at a minimum for breakdown to attend.
 
If I put a "small" lump of meat in the freezer at -18 it takes a fair while to fully freeze (I won't get anal with figures here).

If you know you haven't got enough fuel to get you to a fuel station specially if its freezing out, you 1 - leave a reserve for keeping warm while you wait for rescue, 2 - dont take gamble as to where you will be left stranded, 3 - flat bed trucks still exist. Ofcourse there is always a margin for darwinism.... And if you fuel is of the fossil type always best to take a jerry can full of fuel just in case you run out then wait until you run out and pour it in :rolleyes:
 
To get frozen enough to stop the battery working at all you'd have to be at some ridiculous temperature that doesn't occur in the UK.

If you left a diesel at that temperature the fuel would freeze.. good luck getting out of that one...

Extremes will always be an issue with any technology, and really it's not worth considering when comparing them.. so few of us will ever encounter such conditions.

You can refuel your horse in any grassy field. Stupid combustion engines and their need for dinosaur juice.
 
Left pillar camera blinded so it's going to be an excellent exercise and flood of threads about parking in the dark and no USS :D
Not sure a shoulder height camera facing directly left or right is going to be much use for parking..

They really need to fix this though, my plan is for the MYP to replace the wife's car and be our main mile muncher allowing me to buy something smaller and noisier for a toy, but until the Y gets "bibbers" that plan is going nowhere fast..:(

If one camera is blinded by darkness, means that other cameras can be as well ;)
 
Very few if any of the numerous cars I drove between ages 17-45 had ultrasonic sensors & i never recall hitting or scraping anything.

In those days I was driving RHD/LHD company vehicles totalling 30-40k miles p/a or more & by necessity this included a lot of short urban journeys and constant parking.

I’m not downplaying the annoyance most feel about the lack of sensors but for me it is about by the attitude of Tesla themselves rather than the fact that I am now having to concentrate a little harder, just as I did successfully from the mid 1970’s.
