climate cooled seats would be nice for us folks living in the sun belt.

Ford asking people to wait while not providing any useful information!!! Where have we seen this before?I asked my salesperson about 22 changes and nothing is published yet. He said rumors are a new battery technology along with charging enhancements and probably minor tweaks here and there. I asked if I should cancel my 21 and order a 22. He advised to wait for the official announcement to make an informed decision.
Thank you. I've used parking brakes forever because I grew up with manual transmission cars that don't auto lock themselves, it just became habit. But every time I feel a car bounce off the transmission when it's in park I'm just like 'how do you think that's not worse than just hitting P?'. Like is it really that inconvenient to people to just put on the brake?Put the handbrake on first.
Never understand why so many people let a tiny pin hold the weight of their car when there's a entire secondary braking system designed to hold it for that purpose.
the rollback is easily fixed by applying the parking brake, before putting into park. Maybe, I'm old school, but this is what I always have done on any car I've owned to avoid stress on the parking pawlI'm hoping they figure out the brakes.. the electric motors are capable of stopping and holding the car without friction brakes involved. In a Tesla, the friction brakes are only engaged when extra stopping power is needed. The result is MUCH smoother stopping/starting with one pedal driving.
On a similar note, the parking pawl is unneeded. My car always has a pretty harsh rollback when put into park
Mind you I said parking pawl.. not parking brake. I agree. The brake still needs to be there.Why aren’t parking brakes needed? There are absolutely NO scenarios under which the car would roll without a parking brake? I had a car with a manual transmission once and the parking brake failed. In addition to putting the vehicles in reverse and turning the steering wheel towards the curb, I used a rock as a temporary wheel chock
The electric motors are not able to bring the vehicle to a complete stop or hold the car in place. (except for inclines and even then it would create way too much waste heat so the car uses the ABS system to keep the vehicle from rolling). The magnetic field that generates the negative torque to slow down the vehicle breaks down at slow speeds so the friction brakes are blended in for those last few feet.I'm hoping they figure out the brakes.. the electric motors are capable of stopping and holding the car without friction brakes involved.

I'm just saying a parking pawl is unnecessary as the motor itself can do the same job (and better)
While I agree that its silly to use the motor to come to a complete stop, it is 100% possible and something I do for my profession.The electric motors are not able to bring the vehicle to a complete stop or hold the car in place.

I don’t believe he wasn’t saying that you couldn’t use an electric motor to bring a motorized vehicle to a stop. I think he was just saying that the Mustang Mach E and the Tesla do not exclusively use their electric motors to come to a stop and remain motionless.While I agree that its silly to use the motor to come to a complete stop, it is 100% possible and something I do for my profession.

Well I stand corrected. I assumed that a permanent magnet motor (by virtue of the fact that they are permanent magnets) could not be turned without power.The electric motors are not able to bring the vehicle to a complete stop or hold the car in place.

The Tesla system uses the friction brakes to come to a complete stop. Every time. (Unless Full Self Driving is in use, then it uses some other object to collide with to bring the vehicle to a stop.....)
The parking pawl is there for people that refuse or don't know how to use the Parking Brake.
If you are using the parking brake and still are getting a harsh rollback then your parking brake is faulty and needs to be serviced. Tip: Set the parking brake BEFORE you take your foot off the brake pedal. (I don't use 1PD so I am not sure when is the best time to apply the parking brake for those instances.....)???
There is no way the motor can function as a parking brake. Impossible. The contactors are open when parked and turned off so there is no electrical power available to the motor(s). Some sort of mechanical method must be used instead. Parking brake is the best method IMO. The pawl is there for just in case someone forgets to set the parking brake or the system experiences a malfunction.
Perhaps just a switch to the SK batteries being used in the Lightning. They're reportedly similar to the LG cells, so not really a technology change, but is probably better logistically with the supply chain and cost volume-wise.New battery technology? That seems like a longshot...
