I do not believe this is true at all. A lot of people do not supercharge their car often because it is super inconvenient. You need to wait at least 30 minutes to get over 50% charge. One of the great things about electric cars is that you can charge them at home just like your phone and never need to worry about “do I need to fill up to get to work?” You only need super charger when you are on road trips. So most people use superchargers only once or twice a year. According to /r/teslamotors this perk is worth less then $1000 for the total lifespan of the car for most users (there are a few taxis which use significantly more but not normal users). This is not a lot of money considering the car starts at $70k, can easily go up to $120k and maxes out at about $260k. Edit: the price per kWh is also wrong. Tesla currently sells electricity for an average of 20¢ kWh to consumers which do not qualify for the free super charging perk and they have said they will sell it for 7¢ to semi truck customers. So we can assume Tesla pays between 5¢ and 15¢, depending on the location and whether they have solar and powerpacks installed. Supercharging for free is really a gimmick and free advertising for them because a lot of people who buy such expensive cars value their time above what it takes to recharge it every week. The only reason Tesla built supercharger is because they wanted to enable long distance travel for electric cars.
