Anyone who has lived on the coast knows how HORRIBLE it is to drive out of Houston area when a hurricane approaches. Can you imagine EVs in this 10-50 mile traffic backup trying to get out of town and breaking down? Running out of a battery charge because it takes 10 hours to go 10 miles? Just the visual of this is a nightmare.

A Tesla uses 1.6kwh of power to run the AC while not moving. That means the typical Tesla will be able to idle in traffic for approximately 45 hours before needing a charge.

You guys really don't even try anymore.

But even if the car dies, the wheels can still be steered and therefore my F350 can carefully place the ranch hand on the rear glass and push it off the road, yes?

Well if you are not moving, it doesn't matter if you can go 1,000,000 hours before needing a charge…

So what if you are moving at 5 mph? Now run those numbers. How many hours can you sustain that pace?

He'll just shelter in his Tesla with the AC on, I suppose.

If you aren't moving at all in two days you could just run the AC periodically through the day and extend your charge for even longer. The car uses nothing just sitting there. With 300 mile range going 10 or 40 miles on evac would be a non-issue.

Except you are moving. Just real slow. And I hope these people charge up before they hit the road.

Have you evacuated before? Most people are going almost 100 miles away. It all depends on if you have family somewhere after 50-60 miles or where you can get a hotel.

Also, why don't you floor it and then slam on the breaks. That will constantly charge it and it could run for eternity, right?!?

At 5mph you'd be at your destination in two to ten hours according to the OP's example (10 to 50 miles). EV's power consumption is purely based on power expended. Slower speed slower depletion. And at slow stop and go driving the car is more efficient due to regenerative braking.

Stop and go uses very little energy due to regen..

Let's look at the Rita Hurricane Model. Folks spent 8 hours, burned 3/4 of a tank and turned around and returned back to their houses because they had only traveled 20 miles.

I would love to Calc out the amount of power required to drive an AC in 102 deg heat with a full load and pulling a trailer. I seriously doubt a TESLA can idle and push an AC for 48 hrs in humid/hi heat conditions.

Trailer? Probably 100 miles and AC at keep you alive temp. Or just abandon your trailer like the guy did in the other thread.

Teslas don't idle. They are either delivering power to the motors or not. If it's only using AC it's using 1.2 to 1.6 kWh of power. Do the math with an 82kwh battery.

I guess when you add in what normal people would do (load up everything valuable, things you need to be away from your house, pets, kids, etc) that changes the calculus. We have all seen articles where EVs can't go long when there's more than a driver in the car (or adding a trailer).

You should tell Teslag that… oh wait…

It might be better, honestly. During Harvey - there were effing gas shortages in the metroplex. WTF people.

So now every evacuee is pulling a 10,000 pound utility trailer. My favorite thing about EV threads is the ridiculous amount of goal post moving there is because no one takes the time to actually research EV's.

wait until I perfect my mini-localized EMP device.

Going to spend all my time pissing off the EV drivers. As well as everyone else with computers running their cars while i cruise by in my XJ Wrangler.


So basically everyone with a car made after the late 70's?

We really don't have to research much...after the laws of thermodynamics.

Repeal those and you have a case.

Folks stranded last winter in Fredericksburg, VA. Found out real quick that EVs are junk in storms.

It's a math problem. Kwh capacity divided by kWh use.

No, just a normal trailer. Some people do pull trailers to park at their destination to live in until they can go back. I can tell you have never evacuated. And most people will not be in a Tesla.

A Tesla driver in that storm made it through with power to spare

Dude, have you ever seen the traffic jam out of the gulf coast during an evacuation? It can last for days. Litterally.

But compared to ICE refueling versus charging time, that math does not work during evacuations.

I will grant you that when the electricity goes down, neither is moving if they are "out."

Picture from Rita evac. Internet is full of them. Barely a trailer in site.

Unlike the ice car the Tesla is drawing no power at "idle"

And so can the Tesla.
