The kids drove back from Sydney last night. They didn't charge while down there, and when they got to Katoomba they were already below 30% charge. But the car told them they'd have 22% charge when they got home. And that's *exactly* the charge they had when they drove up the driveway. This is the genius of Tesla engineering, ignore the CEO. They realised to get rid of 'range anxiety', you just make the car super smart at knowing how much electricity is available. That's incredibly hard to do, temperature and topography (how many hills) make a huge difference to range, and going downhill actually boosts your % too. But the algorithm in the system knows to an unbelievable level of accuracy, I've never known it to be wrong. It gets even better because the car will also tell you where to go to charge up if you're going to be short, and how to get there. And you can even nominate a % you want to have available when you arrive home, and it will calculate all of that and route you to chargers and control how much you need to put in, to arrive with that %. You will never be in danger of running out of charge, the car does all that for you.
