I am afraid that it is going to take a whole lot more than Mandarin (and the many different dialects thereof). Baidu and Tencent Maps are essential. Google maps are useless - prohibited. Even so-equipped on their local (not necessarily Galaxy or Apple Smartphones - take the new and very cool Leeco Mobile Phones for example). Locals often cannot find their way around because of the differences in local naming conventions going back centuries even with Baudi and Tencent maps. And then you've got connectivity with insanely popular social media Apps like WeChat - almost unknown outside of those local geographies. Of course you have to enter directions in a mix of (simplified Chinese: 汉字; traditional Chinese: 漢字) characters. Charging stations are called "piles" and are often incompatible both electrically and connector-wise. Competition with electric scooters is fierce - most trips are relatively short range and the scooters can be easily charged in your parking structure or dining room while you are sleeping. Blanketing China with Superchargers? Forget it. They are building bullet trains like mad; highly cost effective with air travel with WI-Fi, food and the Chinese equivalent of Green Cars. Batteries and Gigafactories? Warren Buffet and others have that covered. Baidu is quite far along on nav systems, driver assist (ADAS). You can't do business without a JV. Finally, brand name recognition, service, and support going back decades for makes like BMW, Mercedes, Buick, VW, the Koreans, Japanese, Skodas, Audis, Volvos, etc. is going to be very very difficult to compete with. I spent a good percentage of my time during my last two trips to China studying this, with help from my wife's family and business partners.
