Cybertruck may have 1 million-mile battery

For inexpensive cars electric or otherwise it’s probably just cheaper to replace it at the 12 or 15 year point. For higher end high performance cars like the model S it’s probably worth replacing suspension components, steering, seats etc. Brakes are probably good for the life of the car. I doubt that I touch my brake pedal more than once a week...if that. The cybertruck is stainless steel so less things to rust but the cars are just as susceptible to rust as any vehicle. My wife’s Tesla and my leaf are completely smooth underneath but suspension components are still exposed to road salt etc. The car seems pretty well screwed together. We usually keep our cars for about 7 years. There will still be warranty left on it then. My guess is we’ll have less than 120,000 km on it by then...at least at the rate we are going. :). Maintenance is dirt cheap though. We are in year 5 with our leaf and have gone thru a couple jugs of washer fluid. That’s it. Nada más. Cheap cheap. No oil, no oil filters, no air filters, wires, plugs, hoses, brakes. Woohoo.

Average car goes to the junk yard at around 20yrs. Go check the prices on 12-15yr old high end sedans...just for fun, I plugged in BMW and at 8-10yr old, you are looking at $8-15k for the higher end models.

As you say, you keep your car around 7yrs...that's probably not far from average for new car buyers, so you just proved the point that battery that's good for 50-70yrs (assuming they don't age out before wearing out), doesn't offer much attraction other than hype.

Maintenance on modern new cars isn't much either. Oil changes are typically $25 once a year. Wires, plugs, hoses, brakes...40-100k miles before most of those need changing. So while there is a little maintenance savings, it's not a lot especially when talking about cars that cost $50-100k.
