You arrive by the time of your dock appointment or you lose it. I would expect battery swaps to be the same way. So an appointment is made in advance and what do we do to make sure we arrive in time for appointments? We arrive early. The whole point of the battery swap is to reduce wasted time charging. So how does it help to have to arrive 15 to 30 minutes early to make sure of meeting the appointment, vs. simply spending 45 minutes to charge?

My vision is no longer good enough to be able to do that for these obscured web sites. So rather than read every word, one at a time, I read none of them and visit web sites that aren't designed to torture their viewers.

I like the fact that my vision is not perfect is the reason why you don't read my posts. Interesting. So why do you keep participating in this conversation?

I have tons of time. I don't have the patience to deal with crap web sites or marketing drivel.

Meanwhile, you choose to attack me personally rather than being involved in a discussion of the facts. I think we see where the shortcomings of thinking lie.

Of course there is some sort of diversion, something that wastes time to get the truck into the bay, make the financial arraignments. Get someone's attention to do the change. Or is it fully automatic like a vending machine?

But why you don't address the fact that this is solving a problem that doesn't exist? As I've already shown, a single stop to charge can be concurrent with the mandatory rest period (in the US anyway, not sure what laws are like down under). Someone commented that in the EU there are more/longer rest stops required. So there is already time for charging and no need for swapping batteries. Charging can be accommodated at existing truck stops with the addition of the chargers. It won't require extra land or zoning issues. It's an easy adaptation and can even be blended with the parking spots every truck stop provides. I don't know how large the battery swap buildings would be, but there has to be space for the inventory as well as means to charge them.

I'm having a conversation *here*. You've posted a link to a web site I've already explained I'm not going to struggle to read. If you have something useful to say, please say it. But stop being a horses ass about the simple fact that you are in a conversation you don't like. That has got to be the epitome of idiocy, to be in a conversation you hate, and rail about it constantly, rather than just shutting the fuck up!
