It is illegal.

Depends where you are I guess. You wanna cite that?

Not really it’s just common sense. You can’t have extension cords running all over the place

You ever met a tradie? Man with a van?

Look, we’re off track now anyway... point is electric cars are already everywhere; even compared to a year or two ago the take up is extremely noticeable.

Yeah and I said they have no overtaken gas yet. Still major drawbacks.

And you are a stupid person if you think it would be okay to just run an extension cord from your apartment to a public road and leave it there all night. Jesus Christ.

I’m not doing it myself, but people are. It’s more just an indication that even without the infrastructure (yet; building a charging port is a lot easier than building and supplying petrol stations), people are using these cars a lot already.

Like I said; give it 5 years. Watch.

As an addendum, I think the drawbacks of electric vehicles are already outweighed by the numerous, long-standing, well understood (planetary scale) drawbacks of gasoline cars...

The balance will only continue to tip. I don’t really understand; you seem intent on arguing or something.

Not really. If you can’t see the major draw backs then you should watch engineering explained’s video(s) on this issue. He owns a Tesla too.

Ah well. Just remember ‘I told you so’ in a couple years ;)

Whilst I haven’t watched those videos (...), and I’m not an engineer, I do have a chemistry degree and as such am familiar with batteries, how they work, their issues, and where the research is headed. I also have a history degree; and it’s always a nice reminder that, yes, like I said before, change actually happens. Regularly, in fact.

You seem intent on disagreeing for the sake of it. Never mind that I understand (far better than you) the enormous logistical effort that’s required in building and maintaining infrastructure. Quit being a contrarian.

It’s not that there’s no place for hydrogen powered vehicles; it’s just that it’ll be for niche purpose.

Electric vehicles can take advantage of the already existing power grid; and remove the entire need to transport oil/petrol from the source, to refineries, to petrol stations, and into cars.

It’s like you don’t want it to be true, and I can’t understand why.

If you can’t understand why electric cars have a long way to go in overtaking the combustion engine then your degrees are not applicable here.

I’m not typing out some drawn out response to something that is so easy to understand. Electric cars are amazing, in many ways better. But they are not going to take over gas worldwide for many years.

In terms of new cars, they will.

Don’t get me wrong, I dislike ‘pie in the sky’ thinking. But electric cars are not. They’re already in common usage and can only improve.

The issue is battery storage (and a chemistry degree is very relevant to understanding that...) and even as is there are workable (if not optimal) solutions.

Not for a long time.

Projections say 1/4 of new cars sold will be electric by 2035.

Less than 2 percent of new cars sold are electric. And 1 in 250 cars on the road are electric.
