Cars: 2015

Even still, it still should be calibrated to run like a normal car. Increase the regen when the brakes are applied.

when you step on the brakes it actually uses mechanical brakes to slow/stop the car -- that energy is not going back into the battery, it's lost to friction/heat. "coasting" cuts power to the electric motor but the momentum of the car continues to rotate the motor. When the electric motor is rotated by a force will act as a generator and the resistance will slow the vehicle down. The only way to 'coast' would be to continue to power the electric motor after you've taken your foot of the accelerator and slowly decrease the power or mechanically disconnect the electric motor from the wheels so they can spin freely. That would kill regenerative braking.

Going that fast really screws with your senses. I love a particular story about a driver that got the Veyron up to top speed. When he was about to put it in park and open the door to get out, he noticed he was still going about 40 miles an hour. :D

Not this past trip to Houghton, but last year, hit about 115 in my car, figured, ok, I'm approaching town (5 miles or so out) I'll slow down...ok, doing a little over the speed limit, 5-10 miles I think, look down, still doing 90. Oops. Can't imagine 200.

I do understand how cars slow down. What I'm saying that is should be done is when the brakes are applied, part of that braking force should be the generator pumping up the battery. That does apply a known load that can be compensated by the brake booster when that load goes down some.

Even for "coasting" which would replicate engine braking (remember most cars turn the fuel off these days), you should be generating electricity and putting into the battery. So replicating a normal car would be replicating engine braking, which is slowing the car down, which can generate power. Many modern cars specifically recharge the battery when coasting down.

This isn't hard, it just needs to be calibrated to do that.
 
Re: Cars: 2015

I need help with some electronic issues that I've never seen before in a vehicle.

I have a 2008 Subaru Tribeca. Had the right front headlight (low beam/normal) burn out. When this happened, my radio and HVAC control displays went dark. HVAC controls still worked correctly however. Radio did not turn on/work at all. Since I needed the headlight, I went and replaced it. Once the bulb was replaced, the radio and HVAC controls came back on.

The radio is now messed up however. Auxilary input and CDs function just fine. AM/FM radio is all sorts of jacked up however. AM frequencies show as 891, 883, 748 and other odd numbers (normally whole numbers like 780, 1000, 670, etc.). They also have a limited scanable amount (can't remember AM exactly. Like 730ish to 950ish). FM frequencies are limited from 78.0 to 89.0 and nothing is picked up there either.

Did a headlight going out fry my radio?

I've never seen an FM frequency lower than 87.9 or so.

Really dumb question time: did you pull the fuse, wait 30 seconds, and pop it back in? I did that one day when my radio didn't function, and that fixed the issue.

Have not changed anything other than the headlight...

Those seem very much like a non-North American set up. I seem to recall having a Euro radio in a test car at one time, and could only get the lower bands in the US. I wonder if the circuit was the power to the main memory of the radio...

Crazy Uncle Elon unveils the Cybertruck.

Base model starts at $40K - single motor, RWD, 250 mile range.

High-end starts at $70K - three motors, AWD, 3500 lb payload, 14000 pound towing capacity, 500 (!) mile range, 0-60 in 2.9.

All the obligatory Crazy Uncle Elon bells and whistles available as options.

Only problem is it looks like something out of a no-budget '90s sci-fi movie. And then he broke the windows.

I think the Rivian looks like a better truck

Good Lord fix those headlights, but that actually looks like a truck and that will help with wider market acceptance.

The problem with both is they're focusing more on slick looks and bells and whistles than their target market - the golden goose here is fleet/volume sales. Figure that out and provide an infrastructure for Acme Construction and Jim's Plumbing to start snapping them up 10 at a time and that's ballgame.

Although I admit the Cybertruck would look badass as a Baja/trophy truck. Or do a "Zombie Apocalypse" package for Millennials with more money than sense.

pro climber Alex Honnold has a prototype Rivian for a daily driver. He lives in Las Vegas and is out in the mountains pretty much every day climbing. Pretty functional for an 'adventure vehicle' so far (as long as your adventure is within the range -- Even the White Rim Road loop in Cannyonlands National Park would be doable if you can charge up in Moab first), but yeah the front is a little odd looking.
 
Re: Cars: 2015

It’s not a truck, it’s a joke. But one that is going to win me a bottle of Scotch, so I think it’s hilarious. Bet is whether Tesla’s P/E ratio will be within a standard deviation of the S&P 500 average P/E ratio by 2028. If they go bust or get bought, I also win the bet.

it's going to be a flop, with the Rivian going into production, plus Ford and GM releasing electric trucks in 2021.

The Rivian isn't being put out by Tesla, and Amazon/Ford have invested $1.2B between them. I think they're going to do everything they can to make it work.

A standard deviation one way or the other? Or less than one standard deviation above the average, which is what I'm assuming.
