Actually, talking about it does educate others. There are plenty of folks like you who either have no idea that GM is the "odd man out" with their DC charging standard. GM also seems to have played all their cards on promoting this standard, because the media rhetoric from GM has all but died. Tesla gets tons of "earned advertising" with their very well done standard.
Here's the numbers (again) for each person to consider for themselves:
Protocol .......... US Deployed . World Deployed . US Cars . Worldwide Cars
Frankenplug ........ 2 ..................... 0 ................ 0 ............. 0 ... (moribund)
CHAdeMO ......... 300 ................. 3,000 ......... 40,000 .... 110,000 (growing fast)
Supercharger .... 240 ................... 300 .......... 15,000 ..... 18,000 (extreme growth)
Tesla is a great car.................. Can't wait until their prices get within reason. Never understood their seemly strong desire to exclude others from using their super chargers, but building adapters for Telsa so they could use public adapters. It makes economic sense but otherwise it does not promote the adoption EV's overall for the majority of potential EV adapters.
