Headlights are arguably worth making efficient. The rest is very small potatoes. LED tail and side lights make sense, mostly for reliability.
LED headlights are becoming possible.
Keep your tires properly inflated, and drive like a little old lady.

The ratio would more likely be between 1 and 2.
Many cars would be recharged at home. You would only need a small number at charging stations to cater for long-distance travel.
For the battery handling issue there are already systems being promoted in Japan for automatic transfer of the battery between the car and charging racks. (Of course getting the manufacturers to agree on a standard will be difficult)
I'm not denying that there are many problems and inconveniences and it is not economically justifiable at the moment but it is not an absurd solution.

I have several lithium-ion batteries that have gone duff, in cellphones, and cameras.
3 years seems to indeed be a turning point, capacity loss (like > 50%).

It is a technical engineering term. You would not understand.
Typically the weakest cell fails and then the anti-self destruct mechanism stops the whole thing from being recharged. Officially no user serviceable parts in the multicell units. And the anti self-immolation circuit isn't entirely foolproof there have been a few go up.
The energy density in a fully charged battery is fairly nasty. Even a humble AA when shorted can source well in excess of 10A until it explodes.
And I expect they replace them about every 3-4 years. It is very difficult to make a deep discharge high power battery that is robust in regular use and with a sensible power to weight ratio.

It means they won't hold much charge after a few years of use.
"A lithium-ion battery provides 300-500 discharge/charge cycles..."
"A disadvantage of lithium-ion cells lies in their relatively poor cycle life: upon every (re)charge, deposits form inside the electrolyte that inhibit lithium ion transport, resulting in the capacity of the cell to diminish. The increase in internal resistance affects the cell's ability to deliver current, thus the problem is more pronounced in high-current than low-current applications."
What do you do for a living?

That would be a quality assurance issue.
Perfection is difficult to achieve. But, obviously, everyone else in the world sees the benefit of lithium-ion hugely outweighing the risk.
You can ask...
Lithium polymer batteries are a dream come true for radio controlled aircraft fliers.
Okay, well, maybe you can find someone interested in arguing lithium-ion battery life with you...
Besides being wayward bullshit, Lark, that has nothing to do with lithium-ion batteries dying a "horrible death".
I know better than to depend on wiki s*it to support my arguments, Lark.
Another starry-eyed kid who can't even spell economics.
battery life with you...
batteries dying a "horrible death".
Having to pay to dispose of, and replace, a thousand pounds of exotic batteries every couple of years sounds pretty horrible to me. Gas tanks last for decades.
Menial stuff, huh?
John
battery life with you...

Whatever you say, Asshole.
Very, Lark, I pimp your mother...
I use speech recognition, Geezer.
Starry eyed is the Democrats. Armchair warmongers is the Republicans. Both are politically correct and apparently owned by big oil companies. Neither promotes (nuclear) the viable alternative to fossil fuels. They are all blind partisans.
You need some help.
Stupid, as well as starry-eyed.
Whatever you say, Asshole.
And you, Geezer, such an economy with words...
Really? How long have you been dead?

Do you want to sit there with no lights? That's a good way to die, and take others with you.
Exactly. Whatever I say is true, idiot.
When one word tells all, more are irrelevant.
Yes it is, Lapdog.
A big word!
Speaking of the general subject (politics) Lapdog is reacting to but afraid to talk about... Seems like maybe Lamar Alexander is having an effect on some of the Democrats in power. In Barbara Boxer's committee meeting yesterday, some of the Democrat-invited speakers/witnesses actually mentioned nuclear power.
