To be totally honest, WHY do we even need that crap for the AC charging to begin with.  WHY the special plug, and comms, and cut off box etc etc.  WHY can't that all be done on the fkn vehicle?  All that cord contraption is, is just a fancy switch anyways.  Get rid of all the crap, build it INTO the vehicle so all you really have to do is take out a plain ole extension cord, plug it in and plug it into the bike and it charges?  Now you can park on the sidewalk and charge off the phone charging plug.

It's there so the outlet or cord isn't energized all the dang time. We're dealing with a crap ton of energy and we only want it going where it's supposed to be going.

so you are afraid of household current?  Extension cords terrify you?  That's essentially what you are saying.
The cord is at whatever your mains is at.  It's no different than the cord that you have running from your wall to your computer for you to post.  We better tell the people who have those goofy lights running around their porches and patio's to light it up at night that they are in grave danger!!

To be honest, making YOU bring your own cord might even be safer, because someone as safety conscious as you is going to check their own cord regularly and make sure it's in top shape, unlike say a public cord that can get run over, trashed, cut, you name it.  But it has a switch on it so it's safe.

If you don't want your cord energized all the dang time, simply unplug it from the wall outlet when not in use.  Maybe there's an app for that?

I think you are missing the mark a bit by saying it's not going to work for them.  Perhaps you have bittered in your old age and forgot what it was like to be young and want to have fun.
Well not quite... when I was young I had tons of fun with just 40bhp. The motorcycle industry's chief marketing tactic however is to put you on a treadmill of upgrading to bigger and bigger and more powerful and above all more expensive bikes. That's almost their entire marketing plan. This is also why the motorcycle industry is so fucked.

The perpetual treadmill has seen the complete death of the 600 class as the power outputs spiralled into irrelevance to the point that they were so uncomfortable and extreme and peaky that nobody could be arsed with riding them any more. The 1000 class has gone the same way, with even more ridiculous power output. All the fun's gone out of these bikes, they're just sold to midlife crisis men who eventually realise that actually, they don't want that much power or the aching back or the paranoia any more.

The most fun I've had in the last 20 years on bikes was my 690 Duke. Turns out it is exactly at the sweet spot of price, weight, and performance, and it also turns out that the biggest selling bikes are all making that sort of output too - the MT07, Trident,  etc. I watch with my
head in my hands now as I see the Hornet, GSX8-S, 890 Duke, etc. all doing the exact same pattern of getting ever more powerful...

Anyway my rambling point is, more power is a marketing trick that we fall for when we're young. We don't need more power. Especially not in the EV world right now, as it just means a dead battery in 10 miles. What we need is charging convenience.

The AC charging protocol is, btw, as you describe. There's a demand signal, which is analogue I believe; bike sends appropriate signal down the wire, charger supplies appropriate current/voltage, job done. Nearly all of the control is done by the vehicle. DC charging seems much more complex, likely because of the vastly increased danger, and is controlled chiefly by the charger, which has to be extremely finicky about what it puts out because if there is even the slightest hint that something is not right at the end of that charging cable it could cause instant death, fire, or explosions.

I am happy riding my Royal Enfield with its 20hp as long as I stay off of the freeway. It is really great on two-lane back roads and has the most protective fenders of any motorcycle on the market, which is very useful when riding on wet roads.

Just sold my 27 hp Honda 250cc. Under 99% of circumstances I felt no need for more power. Sure, it was on the limit at 80 mph so freeways were not much fun. I prefer the backroads anyway. The wind at 80 mph is no fun either.  :)

80 MPH no fun?
Naah!!  That's where things just start to get interesting!!
What's not to love about leaning sideways to go straight :D
