    Still not sure what any of this has to do with your belief that they are dangerous.




    Correct.
    It all revolves around high voltage and high current draw in a vehicle that could be mangled and have exposed conductors.
    Higher voltage lends itself to arc fault issues and higher amperage creates heat which helps create imperfections in insulation increasing risk of arc flash. When both are present arc flash or ground faults can be fatal. You combine that with an accident mangling a car and exposing conductors to a metal chassis it can be a disaster waiting to happen. You can smell gas you can see an exposed flame you can’t always see a ground fault or realize that you are about to be the bridge that closes a circuit.

    Look I don’t know the specs on those motors but I know they ain’t 12v or 24v. Here’s an arc flash demo at 480vac.

    I think you should look into the Tesla battery modules. They are not what you think they are.

    Do they store electricity or some magical energy source that isn’t deadly? Look I’m not stupid I’m well aware of modern safety features internal and external to batteries but the current required to operate the motors would be deadly and at high voltage pinholes are life changers/enders.

    It’s worth noting I understand the risk and would consider owning one if it didn’t have to be my primary or secondary mode of transportation. My point is no matter how much you want it to be so Tesla hasn’t figured out how to bend the laws of physics so the electricity used to fuel their vehicles is still significantly more dangerous than traditional sources.

    Im sure we all know proper battery removal in a normal vehicle starts with the negative lead but do you know why? Because if you start with the positive side first you could complete a circuit through the tool and/or yourself by contacting metal with either your body or the wrench. Now consider the voltage and amperage potential of even a Class 8 Diesel are like vape batteries compared to an all electric car

    Electric cars don't make sense for road trips with the current technology. The time to re-charge the battery is too high.

    For everyday driving, as long as you can charge it every night, you always wake up with a full battery at 100%, without ever needing to go get gas or top up.
    I've had a Tesla Model S for two years and have driven it cross country several times. I actually picked it up at the Tesla Fremont factory and drove it back to Baton Rouge. With the supercharger network the road trips are easily managed if you just do a little planning. I like to leave for a road trip about 9am. The first charge stop will be at lunch time. It will be done with charging by the time I finish lunch. Next will be a snack break around 4pm for another 30 minute charge. Then I'll either plan to check into a hotel with a charger around 8pm and charge overnight or I can stop and get dinner while charging and drive one more leg. But I always end at a hotel with a charger and plan charging around lunch or dinner breaks. The best part is the chargers are FREE. You can literally drive cross country unlimited in my Tesla completely free.

    People that have never owned one make a big deal about charging but it's a non issue.

Then tell us if worth it to you to have a vehicle that requires a ‘special fuel source’ that limits your travel to places that can refuel it.
    ?
    Just trying to figure out if there’s a direction you’re heading in. There’s a huge difference in what you’ll get from a gallon of gas depending on what you’re burning it in. There’s also a huge difference in the type of vehicles you’re comparing, besides the obvious power plant. The cost of the ‘fill up’ is less for electric. There are adaptations an owner would have to make as well as concessions that would have to be made with various vehicles. M series BMW’s are great road cars, but no good off road. An electric car wouldn’t be my first choice to go cross country. I can’t see buying a type S Tesla as a primary vehicle. Is it cost comparison your looking for or just pros and cons?

    Example of this technology being employed? I don't mean for consumption, I mean for anything.
    Well we don't rent pigs and I figure it's better to say it right out front because a man that does like to rent pigs is... he's hard to stop.

    Thanks Danny. Just trying to put things into perspective.

    I looked a little at buying an electric car as I was in crummy commute. I recently switched jobs and don't drive my truck much anymore.

    Between that and how I use my vehicle, and electric car just doesn't fit the bill.

    My Tesla Model S is free to charge for the life of the vehicle at any Tesla Supercharger worldwide, Tesla Destination Charger worldwide, or any public charging station in Louisiana (all Louisiana charging stations are free). On top of that, I rent a condo and my electric bill is a flat rate every month no matter how much power I use to charge it at home. My KWh costs for this car are literally zero.
