Sighs- you seem determined that EVs are 'far too hard' when the opposite is true- chargers are readily found (in most countries) simply by looking up the nearest on your app on the phone or on the EVs dash screen.... it even gives you directions and distance lol- almost all EVs these days will warn you on the dash display if you are 'short of power' and helpfully tell you where the nearest charger on your route is even...
20% is what most use as the 'time to recharge point' there's nothing sacred about it lol- some prefer to use 25% or even 30% as their recharge point instead...
We KNOW yanks like to speed- they tell us regularly that they hate our 'nanny state' has speed cameras- which is why the US has the highest death rate per mileage pretty much in the world... and a third higher than the Australian death rate per 100000km driven...
Here the speed limit throughout most of the country is 110kmh/68mph although many rural roads are only 100kph/62mph- exceed the speed limit by less than 10kph/6mph and each time you do it, its 1 demerit point and a $287 fine... exceed it by more than 10kmh but less than 20kph and its $483 and 3 demerit points...if you exceed the speed limit by more than 20 km/h but not more than 30 km/h, the fine is $725 and you will get 4 demerit points. If you exceed the limit by more than 40 km/h, the fine increases to $1,780, and you will get 8 demerit points along with a automatic six-month licence suspension.
If you get more than 12 demerit points in three years, you again lose your licence- mandatory 3 months minimum, park the car and start walking lol (and DON'T think about driving unlicenced- a first time 'no/suspended licence' is a fine of up to $4400 or jail for up to one year for a first-time offender. If you are already disqualified/suspended and keep driving, its even worse, with fines reaching up to $6000 or 18 months in jail....)
It sounds more like the US simply can't get its ◊◊◊◊ together and has done its usual half assed job of doing anything.... Australia is almost exactly the same size as the US, and yet EV sales here are skyrocketing year by year, chargers are readily available so much so that people can drive right around Australia towing caravans in EVs and driving halfway across the country in one is 'just jump in and drive- and let the charge apps take care of your charging needs'
