ELI5:What is so special about Tesla cars?

I understand large companies see them as a huge threat. What makes them so special and why aren't they more mainstream if they are so great?

Tesla make all-electric cars. But what really sets them apart is that they're not the "hippy" electric cars that most companies have been making, but rather something sporty that has enough luxury to compete with BMW or Lexus (and a price tag to match). One of the big shakeups is that they sell directly to consumers rather than going through dealers.
