I honestly don't think we need to legislate anything in regards to phones.
Let's be honest, the company we're talking about here is Apple and their lightning. Most phones sold now are all on USB-C. A lot of Apple products are already moving to C (ipads) etc. This EU push is going to be pretty moot in about 1-2 years when Iphones make the switch IMO. 90% of their products are already C.
I personally don't like lighting, but I am also not a huge fan of govt telling companies how to design tech products. Most of the people making these laws don't even know the Iphone isn't made by Google and openly calls the the CEO Tim Apple in front of Congress.
Do we really want ppl as old as Stonehenge making these laws?
I feel like EV is in the same boat as the early 2000's when it comes to laptops/phones/mp3 players. No one has any idea what's going on, what works, what doesn't. Everyone just wants to be first to market to grab customers. I thnk we'll see a natural progression and standardization on the plug when the market/tech matures a little. The EV market is VERY new compared to the IC.
Let's be honest here, in order for EV to work, we need mass adoption propelled by infrastructure that will support it (charging stations etc). It's really in everyone's interest to agree on one so you don't have to foot the entire bill of creating this system on your own dime. No one is going to buy a car from you if you can only charge it at your stations, it's kind of suicide. Tesla is even letting other cars use their stations now and it makes perfect sense.
I honestly think this problem will take care of itself when all the manufacturers get a few more years under their belts. You can stick a Canadian 120v appliance into a 220v socket and blow it up, I imagine a lot of these problems apply to the EV world. These problems can be solved, but that means costs, which may make your pricepoint too high, or you've got no product to deliver when your competition is grabbing market share in a market that's on FIRE.
The first gas car came out in 1885, the first gas pump that resembles our modern pump didn't appear till 1913.
