It took my grandmother and mother driving from beaumont, to near Dallas, then back to college station and over 30hrs on the road during Rita.

40hrs at idle is great.... now do 30hrs with a several hundred mile drive.

I dont think you've ever been in a hurricane evac, much less a two week stint living on an accidental island with no power...


So we have now moved the goal post from the OP's 10 to 50 miles to several hundred miles.
No one is evacuating 10 miles. 50-100 miles maybe if you have family north where you need to be. If you don't (like having to go to Dallas to get to family), you have to drive through it. Hotels are all booked along the way. My brother had to evacuate 350 miles to get away from Katrina. Why? No hotels.

BTW - he had 9 feet of water in his house.

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.




In 2005 it took us nine hours to get from West Houston to college station. Then the regular time to get from college station up to McKinney, about 3 hours, where we were going to stay with my brother. (I was still living at Houston at the time, have lived in college station then Bryan since 2006)

I seriously doubt the starting and stopping and idling would've made it in an electric car.


EV's don't idle. The motors are using power or they are not.
And the starting and stopping and sitting in traffic doesn't affect the charge?


The starting and stopping is just power draw on the motor when the accelerator pedal is pressed. When you begin the stop you lift off the pedal and it will recharge the battery as the cars momentum movies forward. You rarely use the brakes because of this. Power use is mostly a function if distance not time. Sitting still you'll use 1.2 to 1.6 kWh with the AC on. Turn it off and you basically use nothing sitting in traffic.

Then take it up with the OP. This is his thread. Oh wait, your the OP. Move those goalposts.

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.


I still can't get over the "visual of this is a nightmare" that is something that actually happened, that was entirely gas cars.

To be fair to OP, he didn't say he was traveling 10-50 miles to final destination. He said that the traffic was backed up 10-50 miles. So when evacuating, you are barely moving for 10-50 miles and Then you drive to wherever you're going

That's interesting to know. But again when it took us nine hours to get from west Houston to college station. You sit there maybe move up like for a minute then sit there another five then move up for like a half a minute and then sit there for another 10. It could still sustain in that? Doesn't the turning on and off wear down the battery?

Yes, it would be no issue. It's just an electrical circuit. If you aren't moving it's not on. When I'm stuck in bumper to bumper traffic like that I usually just turn on autopilot and let the car drive for me. I set it to allow two car lengths ahead of me, turn on a podcast, and zone out.

Then there's no problem. I could make it 275 miles or so under those conditions on a full charge.

I don't have anything against the damn things but politicians and marketing gurus need to quit forcing them like if you don't own one you should be put on trial for earth rape.
And quit subsidizing them with tax payer dollars and making it unaffordable for folks who can't use one to have to pay through the nose for fossil fuel energy.

Correct. The later you leave the longer the backup.

But it's obvious Tesla Ag has never had to evacuate. I used the Houston (Rita) example and there were deaths on the highway from people in cars breaking down in the heat. Not just running out of gas. There's a reason the #1 disaster for evacuating is Houston - 4 million in the metro area.

I also gave him the real life example of the Katrina's evacuation. Closest family for my brother out of NOLA was Texas. He went north and it took approx 350 miles away from NOLA to get a hotel. No hotels along the route. He was shocked that it took that far away from the coast to get a place to stay.

Exactly. Nobody likes having this EV **** pushed down their throats any more than somebody pushing the vaccine **** down your throat. I don't see any other car owners preaching like this. You enjoy your car? Great. We don't need to hear the sales job.

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.


How much kwh is a set of 10 year old batteries that no longer holds a charge for a full tank and would be $25,000 to replace with a fresh set of 82kwh batteries?

Realistically, when you evacuate you get it whichever vehicle can fit all your family and crap. And all things being equal, you choose the one with 4WD so you can get back when everything is tore up. So it's probably not gonna be the EV.

I'm watching a news story right now on batteries catching fire and it takes 6 months to 1 year for warranty work. The volt has a recall because of the battery fire risk, but since Chevy can't get the batteries due to supply chain issues, Chevy sent out a software fix to limit the charge to 80%. They will keep lowering the charge percentage to prevent spontaneous battery fires.

The ev haters on this thread are ridiculous with all the goal post moving. So we are now evacuating 100 miles non stop traffic with no charging available and then another 200 miles with still no charging available. Oh yeah and it's in a blizzard while pulling a 10,000lb trailer. Got it.

Saw a report from a couple of days ago about people facing staggering battery replacement charges. Around $25K I think. Very unhappy owners.

This is where I stand. I don't want one and I never want one and I think it's ridiculous that these states are trying to act like this is going to become the norm when it's not at all sustainable at this point. They are actually trying to ban gas cars. This is insane, there's nothing wrong with fossil fuels and there's nothing wrong with gas and oil and coal. Man-made climate change does not exist. All this virtue signaling does nothing.
