The problem so far has been that they cannot produce a car as advanced. Batteries are weaker and the software stinks. The products offered so far are 10 years behind technologically and I think they will have a very hard time competing with Silicon Valley in both aspects.
Tesla is now finding out the hard way that maybe they were a bit too daring with their battery settings (rather than "weak", Tesla doesn't even make their own batteries, they buy them from Panasonic).

So Tesla had quite a few high-profile fires and stealthily cuts battery (useable) capacity and charging speed for "security" and "longevity" reasons.
Is Tesla battery tech really better (again, their batteries are bought off the shelf from Panasonic) or they're just treading a fine line between performance and safety?
A lot of disinformation there, Panasonic manufactures the battery for Tesla using Tesla's specifications. They are not "off the shelf" products and are widely considered the highest power/density of any battery manufactured. Even that relationship is showing signs of changing, indications are that Tesla is about to introduce a much cheaper and cleaner manufacturing process.
Teslas model S and X use NCR18650B Li-ion batteries, which you can buy on any decent battery provider, that are manufactured in Japan and that have hundreds of applications in different appliances.
The model 3 uses another size from Panasonic, the 2170 which so far Panasonic only sells to Tesla, but that has also agreed to be supplied to Toyota. Samsung, LG, etc. also have that size/chemistry.
Tesla only makes the slings and cooling system, but the battery proper is Panasonic (and it seems Tesla is shopping around for different suppliers for the Chinese factory).
