Except the article is saying that they purposely inflated the number it gives.

My (diesel) Equinox gives a conservative range based on actual driving conditions. It is slow to increase a range estimate when I get on the freeway; quick to decrease when I get back into the city, and the actual range available is always 20-50 miles more than the gauge indicates. It is consistently and reliably under-promising and over-performing. If it tells me I can just barely make it to my next stop, I know I can make it, with fuel to spare.

I'd be pretty anxious about range if my car consistently overestimated its own capabilities. When I've been in stop-and-go traffic for the last 30 miles, it should not assume that I'll spend the rest of the charge cruising on the freeway at 5 under the speed limit. If a manufacturer were to use such an algorithm to estimate range, I would say that manufacturer is perpetrating a fraud.

The number it gives is based on ideal driving

No, it should be, but it's not. I'm not going to keep explaining it tho, you should just read the article you're commenting on.

Then you can email the author and explain how they're wrong and Elon is amazing. I'm sure they'd love to hear from you.
