People like the cars because they are better than what the other car makers are making. Model S is the safest, fastest, and most efficient sedan on the market. That's a fact!
Cars are minuscule contributors? The EPA site says 14% Co2 is from cars, which is substantial. That's also a fact!
If Tesla keeps going, it will replace generation and consumption of fossil fuels with a fully renewable cycle. How is that not the best thing ever? That's fantastic! We might be cutting more than 30% of our CO2 emissions.
You need to re-evaluate your standpoint. Also, when you're struggling with cognitive dissonance after reading this, consider this: Your brain's attempts to discredit my argument, and paint Elon backers as mindless followers/disciples, is the real example of psychological trickery, not Elon exploiting some prejudice.
