Assuming most new cars will be EV's by 2030...how to future proof a new home's garage?

How many outlets and how many amps would be required? I read somewhere that 100 amps per parking space (example - 3 if it's a 3 car garage), but that seems excessive. I do imagine that at least a 50 amp outlet somewhere outside the garage for cars parked outside might be needed.
For those of you with newer EV's or those of you that understand this topic....how would you wire up a 3 car garage if you could potentially have up to 3 EV's in 10-20 years?
Other than additional outlets, what else would need to be done to future proof a new home for this additional electricity demand?
ETA: If this is more appropriate for the Home/Garden board, please move it there.

That's a bold assumption

I think my next vehicle, which will be a cheap pickup truck, will probably be the last ICE vehicle I ever buy. I will try to keep it forever, but most of the new engineering and investment by the big auto companies are going into EV's.

I’m pretty terrified my ability to run my home on gas/natural gas will be prohibited in case of power outages due to storms and hurricanes. Entergy can barely keep the lights on as it is.
If I lose power today it’s no sweat because I have an independent way to power my needs in a pinch. The further we move away from gas less my options are to keep my power on in an emergency.

Don't worry about it. We'll all have Mr. Fusion retrofits by then.

If the power is out the gas pumps won't work anyway

You’d just be guessing. I’d say cross that bridge when you get to it.

I guess you can spend a fortune on a solar panel array if you wanted to, but the folks I know with them in Chicago almost never produce enough juice to power the home and have to rely on the electrical grid. Louisiana has slightly longer days, so it may be different.
Is geothermal an option down there? Some people in Memphis had that when I lived in that area.

It's a concern. People use gas a lot for cooking so there will likely always be that service in our lifetimes. It just may become much more expensive if they clamp down on the energy industry.

Building a new house soon. Was going to give it a shot. I really like the Tesla Model X.

Yea that's going to get interesting. Most modern homes have 200amp panels service wires. Older homes may only have 100 amp panels.

I think the "special" home charger for the Teslas requires a 220V hookup, just build one out like you would for a washer/dryer.

Do what you want bruh.
I'm not buying an electric car in the next 9 years.
what if you park on the street? We just gonna have big arse wires everywhere? Is the electrical infrastructure ready for the enormous increase in power?
It's just a stupid statement made by idiot elected officials to think this is feasible.

I have an unused 100 Amp service already in my garage, the folks who originally built the house had a electric kiln in the garage. 
A completely electric car would work for me for at least 95% of my travel.
The other 5% I could either make alternative arrangements or deal with recharging mid trip.

Better find a friend with an electrical socket and a long extension chord.

Do you think it would require 100 amp service to every parking bay? Would 50 amp suffice?

I know who you voted for

Don’t forget the whole house generator that will be needed for power outages.

I may have been a registered Democrat for the last 10 years and I may own a Subaru station wagon (with a Thule) and a Volvo. But don't assume I'm stupid enough to vote for any authoritarian prick that wants to cripple our nation and eliminate rights. I also owned a shite load of guns before that last tragic boating accident and I grew up in a neighborhood of plant workers, cops, and mechanics.
Recognizing the direction we are headed isn't the same as embracing it.
Not saying I like the idea of people being forced to spend a fortune on electricity and vehicles because of some political war against the oil and gas industry. But it's clear that all of the big car companies are spending much more on EV's than ICE cars right now. The new car market will reflect that in a few years. The coolest, nicest new cars will be EV's very soon.

I think the current Tesla charger maxes out at 48 Amps. It’ll work with much less, albeit slower.
