Public transport will never recreate the freedom of car ownership. It’s a collectivist dream not rooted in reality.

Rarely in everyday life situations do I feel as claustrophobic as being in a car in traffic in a typical road.

Can’t change direction (one lane no junctions), can’t change speed (vehicles in front and behind), can’t stop (flow of traffic), can’t break concentration (driving), can’t change body position (car cabin is tiny, seats and hand/feet controls are fixed, no space to stand), can’t look away for more than a moment (responsibility of driving).

And the only places to go are on the predetermined road, from a car park, to a car park, following a lot of strict prescribed rules about how.

This meme of “freedom” is brainwashing and marketing (which has been picked up as an identity thing by the right wing recently).

There’s nothing free about having to use a $20,000 vehicle to buy bread because no other options are available.

No surprises. No matter how we look at it, EVs are much friendlier and safer to the environment. Some people argue the source of electricty can be contested against because that involves fossil fuel burning again, but in today's world we are rapidly moving away from it and towards nuclear/hydel/wind methods for generating power. I hope ICE cars completely become a thing of the past in the next couple of decades to co…

Even if the fossil fuel argument at the source was/is valid, it's infinitely more efficient to do it at the source than in a car. You can extract far more energy and do better to mitigate byproducts.

Also, an EV is as green as the grid. Hamburgs public transportation is heavily investing into electrical busses, because a bus is expected to function for 10 - 15 years. Meaning, a diesel bus built today will be as polluting in 2035 as it is today, though they are also looking at alternatives there. But an electrical bus will become cleaner and cleaner over time.

They are still a luxury item, only affordable by a few. Although to be fair new ICE cars are also a luxury item. Most people can only buy used ICE cars these days

In the US, that is. In China, several EV models sell for under $10k, with some, like the Wuling Hongguang Mini EV, starting as low as $4k [0].

The pollution and grime that cars produce comes from tires rubbing off, not exhaust. (The exhaust pollution is mostly invisible.)

Electric cars are heavier and produce more tire grime.

I do not own a vehicle, and most of my life I've depended on public transit. Lately, I take Waymos or I ride scooters, or use public transit as usual.

Sometimes, for special errands, I rent a car. For example, I intended to move across town last year, so I rented a car for 3-4 days.

It was the most excruciating pain I could have. I chose a little Mitsubishi Mirage, and firstly, it was the middle of July in the Sonoran Desert, and the A/C hardly worked, so I was sweating, and the car would heat up real good in parking lots. No sun shades, dark upholstery. Also, the USB connection was flaky, so sometimes my phone didn't charge, and whether or not, it was directly exposed to the Sun and overheating.

By the second day, my legs hurt a lot. I had spent an unexpected amount of time on my feet and walking around, despite the vehicle. Do you know how big parking lots are these days?!

I tried sitting down at every opportunity. I have a running gag/dispute at my bank to see whether they will allow me to "sit down" at the "ADA/Disabled" teller window.

Driving home at night on the last night, my leg cramped up really bad. I was in such pain, I nearly pulled over because it was my accelerator/brake leg and I was going to lose control of the car.

Thankfully I was able to hold it together, and returned the car the next day, but boy I did not want such a vehicle ever again. And it was not a stick-shift; it was an automatic transmission.

Next time I'm going to be really sure that the USB and A/C work. And that my legs are super-comfortable and has cruise control.

Backup cameras are an enormous safety improvement. Plus touchscreens are much cheaper than buttons and knobs.

Backup cameras are an enormous safety improvement. You know that a backup camera can be added to practically any car right? My ~2002 Toyota has a Pioneer deck from around 2007 (I guess?) that supports reversing camera input. My wifes 2012 Toyota hybrid has a reversing camera using some POS cheap Chinese deck that's so shit it doesn't even support Bluetooth audio. No part of reversing cameras are dependent on any of t…

I responded to a comment about screens.

I know I will be damned for this comment but nevertheless even EVs produce pollution with regard to tire abrasion. Tire abrasion itself is the main contributor to microplastics

Recent research suggests the issues are much less concerning than previously estimated.

God I love freedom so much.

Tires and brakes still contribute to a lot of particulate matter pollution even from EV's, but they're at least a step up. The best EV's are still eBikes though.
