Another big problem with these deluxe golf carts is that they don't make any engine noise, so if you're walking in a parking lot and happen to be passing behind a Tesla driven by someone with the "start her up, immediately shift into reverse, and step on the accelerator without looking" attitude, you aren't getting any warning that you're about to be run over because there's no ICE to crank. It's also bad when you have weather conditions that greatly reduce visibility and standard procedure at a rural intersection is to roll down the windows and listen for cross traffic, since Teslas don't make any engine noise. They ought to be required by law to have a pair (for redundancy) of weatherproof speakers playing appropriate engine noise MP3s when in operation.

Sadly, they do now.
In the US.
It makes it much harder to run over people who need to be run over.

It’ll consume 78% of your battery life, so you’d need to charge before you leave and hunt for a charger when you arrive. And I don’t know about you but I get anxious when my phone drops below 30%, and 12% is low enough that I could really face the possibility of being stranded if conditions aren’t perfect or it takes too long to find a charger.

Funny enough, mom did drive a Subaru when she was working. She was a mail carrier and had to drive her own car and they were one of the few companies that sold right-hand-drive cars in the US.

Not a troll, but maybe a little hyperbolic. Google Maps is an estimation of journey time. It makes the assumption that you aren't going to need to make stops.
So a refuel, coffee and toilet break at the motorway services.
- You have to slow down on the highway to pull off. You need to get into the right lane, maybe go through some intersections. So we will say (2-5 minutes).
- You have to then negotiate the services. (2 minutes).
- You then have to fill up. (2 minutes).
- Go to the loo (2-5 minutes).
- Get a coffee (2-5 minutes).
- Pay (1 minute).
- Go back to the car, put the phone back in the cradle, start the car, etc. (1-2 minutes).
- Go back out (2-5 minutes)
- Get back on the motorway (2-5 minutes)
In an electric car the recharge stop needs to be much longer. Sure, you can do some of those other things while you are waiting to charge. This is on the assumption that there are spaces to charge (which I've noticed there often is not).
But it's still going to be an additional 45 minutes to 1 hour for the journey time. If you have to do that twice, that is 1 hour 30 minutes. So a 5-hour journey can turn into a 7-8 hour journey easily.
It is like F1. The time lost isn't them doing the tyre change, as that is like 5 seconds (or however long it is now). It is the time lost on having to slow down and enter the pit lane that loses them the most amount of time.

The reversing AVAS on a Tesla is actually fairly loud, well done w/r/t safety, and easy to identify:
The forward AVAS, though, is barely audible and only loud enough to comply with regulations, it's kind of a noise-ish thing?:
Completely insufficient compared to what the reference in AVAS, Toyota, does on their hybrids (And has been doing so for over 15 years now!):
The science behind AVAS is actually pretty cool when it's done properly (and not half-assed like Tesla's forward AVAS).
You need:
- To be able to guess how far the vehicle is without having heard the AVAS before
- To be able to guess whether it's approaching or distancing
- To be able to guess speed
- To be able to find the direction of the vehicle fairly precisely
Most of these engage the field of Psychoacoustics, and is a fascinating rabbit hole to fall into if you have a few hours to throw away.

That sound is the equivalent of the Firealarm chirping noise, never understood why it's that hard for making loud enough EVs without resorting to speakers..

Because you need something to make the noise, making anything else that isn't the speaker either does not pass the requirements for AVAS laws, or is too big a compromise VS just throwing a handful of watts into a speaker.
Problem is, a noisy motor means any of:
- It's under high load, so you either need a proper multi-speed transmission (very lossy, highly complex when compared to a 3-5 gear transfer case), or you can't go fast
- Has a bad inductor design, meaning it heats up a lot, and has shit power
- You're injecting HF noise into the coils, which makes the motor heat up while providing zero torque
- Has straight cut gears in the transfer case. I love the sound of straight-cuts, but it would be UNBEARABLE for long drives
Racecar with straight cuts:
Rally EV with straight cuts:
You could also abuse the AC compressor or overdrive the DC-DC converter. Both of these would cause a lot of wear.
The actual solution is to come up with a less poofy sound to go out of the speakers.
But it looks like EVs are better at getting people to suck cock than being a victim of Bacha Bazi, thus all AVAS sound designers need a cascade of cum to output anything.

Like Pikes Peak and other hill climbs that make microwaves play some loud sounds to alert spectators and wildlife, but mandatory to be something gayest and most embarrassing.
