Yup, people are just that way. 100 cars crash and people thinks it's normal. 1 autonomous car crashes and the technology is a failure.

Check out what police departments pay for fuel and gasoline engine and transmission repairs.


in the article it was stated that the PD bought it used.
in a prev. article linked within that article, it was part of a pilot program ["The electric patrol vehicle pilot program is an extension of the City's clean technology and smart city initiatives to help make Fremont a more sustainable community," said Fremont Police Captain Sean Washington in a press release.]

they bought a used 2014 model, added lights/pushbar/ballistic barriers. they estimated if they had purchased an explorer instead,over 5 years they would spend $32k in fuel, and another $15k in maintenance. I'm sure that potential $47k savings contributed to the decision/offset the additional costs.

As much as I don't care for Tesla, this is in no way the fault of Tesla since running out of gas can and will happen to any other pursuit car. Now if the car shut off and started to update in the middle of a pursuit, that would be something else.
 
Total clickbait.

Didn't plug it in= didn't fill it up.


Add in "Didn't pay attention to the gauge"

UD
 
My question is how do they end up charging it if it runs out in the middle of nowhere?
Do they ended up towing the car?
Why don't they dispatch another unit and continue the chase if they want to catch whoever it is?

Not a good car for pursuit work. Even if it is fully charged. A few years ago, Car and Driver ran a Tesla P100d in the Lightning Lap competition at VIR. 40 seconds into the lap, the Tesla went into thermal protection mode, and slowed down. It did finish the lap, but at a greatly reduced speed. But 99 speeders out of 100 aren't going to run, so the Tesla would be OK in most cases. I just wonder how well it would do if the officer has been sitting for hours taking radar readings with the A/C on, drawing down the battery. This is important in sunny Southern California. It would be impractical to keep the car plugged in so the A/C doesn't draw down the battery. What is the officer going to do? Jump out of the car and unplug the cord, then get back in and chase down the speeder?

The pursuee would....
 
OTOH if that Tesla was fully charged it would catch up to a brand new Z-06 Corvette. Try that with a regular gas cruiser. They can always radio ahead...crooks and constant violators are basically their own enemy and will get caught sooner or later. I like Tesla's and Corvettes but just making a point.

A good point. Another consideration is that gasoline stations are everywhere and the patrol car can be refueled in minutes. The Tesla? Perhaps not as convenient though I imagine that in Fremont the charging stations are more plentiful than most places. The time to charge is a concern.

As mentioned previously, this is probably a feasibility test.

Well, you can't outrun Motorola. Or a chopper. Or a bullet.

yeah....blame the police for bad behavior. Great job!!
 
Yep ... all kinds of stuff in Texas named after a young game warden who gave chase after a guy who shot a varmint ...
The outlaw hunter killed the LEO in a shoot out

Never understood that one ... not many do.

They go over 300 miles on a charge. How much do you need in 1 day?
 
Man.... all this negativity.....it's a step in the right direction isn't it? Very few things very new work perfect from the start. I've known many dopes that run out of gas for their cars. Why wouldn't Tesla try and market it to police departments? They're in business to make money too.

One, I don't know how many miles these patrol cars accumulate on a daily basis, plus you have the idling considerations and electronic usage like computers and radios.

Two, battery efficiency declines over time. They may have a 300 mile range brand new ( and that depends on a number of variables) but 3-4 years down the road what is that capacity?

I'm not against electric cars. The project should be geared more to the municipality general fleet use. It's interesting that we haven't seen that yet. It might be popular in California but most other places Tesla is still very much a minority vehicle.

Isn't that BEST case scenario? Not over 300 city. That means that at least half of the days I drive my vehicle for work other than to the local plant, I would have to stop for recharging. Gasoline, I get 10 minutes for a fillup and lightening my liquid load and I'm back on the road.

IMO, the only people that EVs make "good" sense for are those that live outside of the metro area proper (i.e. no public transportation) and within at least 30% of the EV's range (so you can make it home at night) while allowing for traffic etc and not having to recharge during the day. EVs likely will never work for people like traveling salesmen; as I've posited before, it's almost as if governments are wanting to drive less travel by pushing purposely limiting technologies. If you live in the metro proper, use public transportation. Best case as far as I see it.

Only if it manages to successfully stop the Z06 within a 1/4 mile. Anything beyond that it's rapidly disappearing in the Z06 mirrors.
 
A few points:
EVs do better in the city than freeway for many reasons, primarily to regenerative braking.
Efficiency of regenerative braking can be astonishingly high. Recovering half of the electricity used for acceleration during the phase of deceleration is common.

Model S top speed is software limited to about 160 MPH on the base models.

There is not enough data to predict battery degradation and life. .
Current data shows less than 10% after 160K miles. The P85 battery pack is guaranteed for 8 years unlimited miles

I hope this helps.
