Very poor people need fleet car like hen house car, It will replace bus and taxi, but if you have enough money to buy car you don't want to share a car with strangers. It's human nature. People want to take their own driveless cars. Car is not just transporter. It's your face and pride. I don't...

Because Tesla is building so many infrastructures like supercharger station, service center at China & Japan. Tesla will wait until building enough infrastructures.

I think Tesla will give away patents to other auto makers under the terms of exclusive contracts like sole distributorship of battery pack. and they will announce building multi gigafactories soon.

I think Future EV cars(Gen3) need to 50kwh because Gen3 is the smaller than model s. I suspect supercharging technologies will improve significantly in 3~4 years and full charging time will be less than 10 min. Consumer will realize they dont need to 100kwh.

This means Tesla will partner with automobile part suppliers like Foxconn, not other auto makers.

Now Tesla don't need to make partnership with other auto makers. I think Tesla will partner with other auto makers after 2020(success of Gen 3, half million per year). When Tesla build 2nd, 3rd giga factories, they will give away patents(supercharging & power train technologies) to other auto...

I know Model s battery's charge cycle is 3000 until 80% of total capacity. Probably battery packs will last at least 20 years.

models s battery is not normal battery Model S battery is not a normal battery. The battery need something special ingrediants. There is youtube video about Models s battery. Why do Li-ion Batteries die ? and how to improve the situation? - YouTube

I think Tesla is not using compressible layer. distance between ballistic shield and battery back can be increased from 1/4 inch to 2 inch according to the patent.

Perhaps Tesla already has improved undercarriage protection of new cars. here is the patent about battery pack protection. http://www.patentlens.net/patentlens/patents.html?patnums=US_8286743#tab_2

The most important point is that the model s has weakness from road debris as compared with other cars, because the battery size of undercarriage is larger than other EV's or ICE fuel tank. we know that, but no one talk about the issue. Eventually undercarriage protection ability of modes s must...

How about attaching liquid metal at front part of aluminum plate amour. The liquid metal is 10 times stronger than aluminum in the same thickness. I think just small liquid metal is enough to protect battery from metal debris.

If Average production rate is 105/day(525/week) in Q3, total production number of Q3 is 6720 cars.(105 x 64days = 6720 cars) 5150 cars delivered in Q2. Production rate would be 95/day(475/week) and total production number of Q2 is 6080 cars. 930 were not delivered in Q2. 4950 cars delivered in...
