150 miles would be great. When you get around 60 miles, it means a lot of places become "can't use the EV today." I've driven up small hills and after about a mile, my EV loses about 5+ miles. The other issue is the charging stations. I went to a Blink station last night and it was at some office complex. So it was late and nobody was around, but there was also nothing in walking distance around. So i had to wait. Read a book , but still.
And even though it was supposed to be a Level 2 station, I was there for over an hour and i gained about 10 miles. I left my office with around 11 miles, got to the blink station with 9 miles, left the blink station about an hour and 15 minutes later with 20 miles. If you have a car that avgs about 60 miles of driving and it would take over 6 hours just to charge it on a Level 2 charger, that's a problem.
One issue I have is with people who keep saying Tesla is going to have this or that. Tesla has a $100K car. Maybe people haven't tried to buy one or know the realities, but I've seen plenty of people say "after rebates it's only.." except Tesla includes a lot of marketing BS in their pricing. That $7500 is already included. You can be cheap and wind up with an $85K car, but that's about as cheap as you'll get that damn car if you actually want to use it. So yeah, they keep saying they will build a $50K car, but their next model, the Model X, is going to be more expensive than the Model S. It's more like an SUV. It might get less than the S, but it'll have more room.
So the reality is, Tesla might have a $30K car in the year 2025, other than that, it's up to the big manufacturers. And Telsa now needs to start relying on actually selling their cars instead of making more money on Energy Credits they were getting from the Big Auto companies. Now that the big auto companies have started doing their own EV models, they don't need to pay Tesla for compliance. And we've already seen Tesla take a hit in revenue because of that. If you look at their numbers, they are the most popular EV, but they also don't have anything else to sell and they don't have any $20K car that millions of people are buying. I would love for Tesla to succeed, I just don't see a cheap car from them anytime soon, and maybe never. They might just be that niche car company that sells $100K cars.
