I'm pretty sure that electronic cars are the future, i don't own one myself yet but i want to once the oil reserves dry out there will be the need for
another kind of fuel for cars and electric cars are a step in the right direction. I also think that a lot of people will still drive normal cars until the oil runs out because of the sound and the feeling that you get with a regular more specific fast car or a muscle car for example, but maybe we could solve the sound issue by installing a hifi surround sound system imitating a muscle cars noises

The oil reserves won't dry in your lifetime, don't bother waiting for that, just buy it at your best convenience, preferably before all your local gas stations disappear (give it a few more decades).
As for the noise, i particularly like the subtle (but noticeable) electric motor noise. Cities will have a much better sonic environment in the future.
Check the many youtube videos about Tesla owners, search for "tesla smile" where they give people rides to see their reaction when flooring it, there you can listen to the electric buzz kicking. It might not wake up your neighbors, but you
will feel it...
When oil production peaks globally, it won't disappear the next day. Supply will simply slowly decrease, and price will slowly rise to compensate, which will in turn increase the demand for electric vehicles, and perhaps production.
Granted, Tesla's are luxury cars, over qualified for someone doing a daily commute, but Elon wanted to change the worldwide perception and challenge all the established companies, which i think he did successfully. From his efforts the whole world benefits (he released the patents of his electric engines for anyone to use). The model 3 is cheaper, but still a luxury. Probably the cheapest pure electric cars won't come from Tesla, maybe from China or such very compact 4 seats at best.
I don't believe in hybrids, they are a dead end, and are more complex (and heavier) than what its needed. The simplicity of a pure electric is its beauty, and people habits must and will change. Just remember: Park and plug, never forget.
