I also don't think Tesla needs to drop prices, if anything they should increase the price to increase their margins and could justify it with the enhancements they are now including as standard (even faster charging capabilities, driver assist cameras, etc).
the demand for the S and X is way beyond supply for the foreseeable future in my opinion, there is so much untapped demand that Tesla is trying to tap slowly as they increase supply
what if demand rises to 500k annually for the S and X? And what if it continues to rise? That brings up an interesting question...do they delay the Model 3 indefinitely until they can meet demand for the S and X? Or do they starve some of the 90k car supply in order to build some 35-50k Model 3 cars while they build new factories to catch supply up to demand
