Uh, there's plenty to wear out. Unless you truly care for your car cosmetics is the first thing to go (and the hardest and most expensive to fix). Plus, there's still plenty of electronics to fail, suspension bits wear, etc. Most importantly, the battery will lose capacity.
And let's not forget there's always something better and shinier sitting on a showroom begging you to drive her home.
This thread is all over the place, but I did want to respond to this post. Whenever I am talking up electric cars, I say that they have much less maintenance, and this is very true. The battery rebuttal is usually the first one I get, and it is not without it's merits. I am not in the auto repair field, but from my personal experience and anecdotal evidence from friends and family members, the batteries (both Ni-MH and Li-ion) are not as unreliable as some people think.
Consider the cost of maintenance items an ICE must endure for a 150K+ mile life such as oil changes, spark plugs, valve adjustment, timing belt/chain, filters, various emissions components. Depending on manufacturer, you could be paying a lot more or a bit less than a new battery on your BEV. With the electric vehicle, you also get the benefit of doing less brake jobs, or none at all if you don't drive aggressively, and have a vehicle capable of great regen.
You raise a good point about electronics, as they are prone to failure just the same as mechanical things. I don't know too much about Chevy's battery electric cars, or Nissan and Mitsubishi as well. I have always admired the Volt, and the scope of the Leaf and MiEV, I think Toyota really laid the groundwork for the counter to the battery argument. That is why I am disheartened they are skipping Li-ion and trying to go fuel cell with the Mirai. Anyhow, even ICE vehicles have a large amount of electronics to make the engines function within emission and power specs. I am not sure if you are implying that ICE cars are still running breaker point distributors and carburetors, but the failure-prone electronics is a check mark in both power sources, IMO. I get it that you are just responding in a realistic fashion to yinan's overly-enthusiastic post, and I am not trying to deride you, just keeping the facts straight.
I am probably in the minority where functionality is more important to how a vehicle looks, so the cosmetic argument is moot.
I am not going to grandstand for Tesla as yinan has embarrassingly done, but I believe the Model S is one of the most properly executed arguments for battery powered electric vehicles on the road today.
Also, I don't like the screen in that Model 3 interior one bit.
