Daishi June 11, 2018 03:33 PM 620 miles seems like a lot of range for something that far into diminishing returns on acceleration. It makes me wonder if they will offer a separate light weight high throughput performance pack with much shorter range. aki009 June 11, 2018 04:21 PM For myself I'm waiting to see what types of tires this car will have. 0-60 in sub 2 seconds requires some impressive tire technology, which might not be street legal. It'd be a real bummer to have to settle for "only" sub 3 second performance because of tire limitations. paul314 June 11, 2018 06:16 PM If you read the stuff about max discharge rate in the ultracapacitor piece from earlier, it makes at least a little sense. To get super acceleration, you need ridiculous amps of current. But if individual batteries are current-limited, then you need an enormous battery pack with batteries operating in parallel. The resulting range is merely a side effect. Mr T June 11, 2018 10:23 PM I think Elon is having a laugh at the expense of all the gullible people out there, rocket thrusters would never get past safety requirements in 99% of countries. Of course, in the US you seem to be able to put almost anything on the road, so who knows, maybe he is serious.

Tomzi June 12, 2018 03:26 AM how many empty words. and people still finding him as a inventor. what a said moment for humanity. Grunchy June 12, 2018 01:00 PM I heard the real reason Elon shot his old roadster into space is because it was cheaper than fixing the failed battery ha ha. (Apparently, fixing an out-of-warranty Tesla is outrageously expensive). Speaking personally, I don't want a rocket car, I want a jet car. The batmobile. An onboard jet engine. What this probably means is some kind of diesel-electric system. That's ok with me. If it works for freight trains, and it's got a jet engine like batman, these are all positives for me, I would be a customer.

I've only ever heard him referred to as an entrepreneur or as an innovator. He's certainly both of those things and with great success.Second, what's "empty" about the announcement? Is there proof it's a joke or not technically feasible?
