Show the sneering Prius owner a picture of the dirtiest most poisonous mine site in China,
explain that's where cadmium and other special elements comes from.
Next a picture of the dirtiest smokiest factory in China,
explain that's where the cadmium and others plus even more dirty stuff made into their batteries.
Remind them that that's just the batteries, the motors have a similar and even longer pedigree.
Saddest part: it ain't that far from the truth.

Cadmium? More like Lithium if I'm not mistaken.
Edit: The <i>Prion</i> has NiMH cells. Very conservative. I'm surprised.

In a conversation yesterday, someone said in 20 years, fossil fuels vehicles will be obsolete and we will all be driving electric vehicles.
So.. let's look at that.
Most transformers are designed to provide power to up to 4 hours; if each house has an electric vehicle, the transformer is not designed to provide that much power... it is designed for current residential use.
So... who doesn't get a full charge?
Also, transformers in operation are designed to cool down overnight... during the lower use period. If you are charging your vehicle at night, then the transformers doesn't cool down which reduces its life span. The utility company can replace the transformers, but that will increase your monthly bill because they have to recoup the costs.
There is an established fuel delivery system for gasoline and diesel. Who is going to put in all of the charging stations along the interstate highways and maintain them? What if you pull in to recharge and all units are busy? Are you willing to wait a few hours?
Food for thought...

One of the mechanisms that most EV folks talk about are universal batteries/battery swapping. i.e. you don't pull into a station to recharge, you pull into a station to swap battery packs, and the recharging happens elsewhere.
Now, whether or not that becomes a reality in 20 years is another story.

That would require every vehicle to use an identical battery pack. (Phyiscal size, voltage, peak discharge rate, cooling, etc). I'll let you decide how likely a result that is.
On paper flow batteries could fit the bill by letting you refill your cars battery similar to how you refill your gas tank; but the energy density of the liquid eltrolytes they use is several times lower than that of LiON batteries.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Depends on where you live. To my house, I've got a 230V 3-phase, 63A circuit that can provide 25 kW effect; that is not too uncommon around here. The average Norwegian household exceeds 20.000 kWh yearly consumption; for detached houses it is closer to 30.000 kWh/year. And that is with 20 cm insulation being the standadard for a generation; for new buildings today, 30 cm (12 in) is common.
I don't think I have ever consumed 25 kW effect. But if I go to my sauna (7 kW electric heater), my hot water heater (2 Kw kicks in) at the same time as the kitchen oven chooses to boost the heat for the steak being prepared (2,7 kW), my washing machine engages its 2 kW heating element and my (future) electric car draws a few kW in the garage, I don't want my main fuse to blow.
The power company really wants us to move as much as possible to nihgttime hours - preferably after midnight. We are in a transition to 'smart meters', and in a few years, we might have 'special offers' on electric power bought at extremely low prices (a cent pr kWh or less)from middle European countries who cannot crank down their oil or nuclear power plants every night, so they must get rid of the nighttime power somehow. We can easily crank down our hydropower plants at night, saving the water for daytime when we can sell it at a very high price to the same middle European countries, when their oil/nuclear plants do not have enough capacity to cover the industry/business demand for power.
Actually, we do have a small bottleneck in our power distribution network - the hydropower plants can generate all the power we need, but the power lines are somewhat underdimensioned for two winter weeks at 40 below zero. So evening out the load to avoid the high peaks is essential, and stimulating owners of electrical cars to do the charging at night is an essential part of that. When we get the smart meters in place, most homes will have a subscription where the max power drawn in any hour of the month sets the price for that entire month (rougly speaking; this is a simplified view), so it pays back to even out your power use.
There was some discussion lately about those 'fast charge' stations: In cities, they may be busy a significant part of the day. Along the highways, utilization may be as low as 1-5% of the time, but when active, they need huge supply cables from the power company. Then there are public regulations on 'fair and non-discriminatory pricing' that requires the power company to charge as much for the power line to the 5% utilization charging station as they charge an industry customer drawing a steady 95% of the max effect 24/7. So the power line cost makes up for the great majority of the expenses, not the cost of the electricity itself.
So, most people with electric cars choose to charge them at night, at low effect (typically 2 kW) over many hours.

Obsolete, eh?

Staged charging over night and/or something like trickle charging could/would/should happen.

There is also the concept of photo cells on the vehicle itself. This would only charge during the daytime of course and would be a very slow charge rate. Perfect strategy for a commuter car, poor choice for a transport vehicle.

While Texas is a right leaning state (ie. Republican), the capitol city of Austin is very left (ie. Democrat) with plenty of limousine liberal tree hugging politically correct environmental crazies.

I was looking for CURBSTONE, but KERBSTONE is a variant spelling and I'll allow it.
