Formula E has only been around since 2011 and has evolved quite rapidly. One major example is the batteries and how they used to have to switch cars half way through a race to a fully charged car. The upcoming cars are only on their 2nd generation and will now do a full 45 min race on a single charge.
Lucas di Grassi also talks about the concept of disruptive technologies which I found quite interesting. He compares Formula E with the advent of the internet. People laughed at the idea of doing certain things online in the same way as they laughed at Formula E when it started. We now do so much online including a lot of our shopping and banking.
I must admit I still find Formula 1 more exciting but watching this video made me see how this is likely to replace Formula 1 in the future.
As manufacturers begin to take electric cars more seriously this is the perfect place to test new technologies and hopefully advance things even more quickly.
