Right, those sound brilliant on a lawn mower deck to flush out grass clippings until they plug with grass so this clearly needs a re-think as well.
Sell me on EVs.... VAG or otherwise...

@Dana - you need Mo Water POOWAR to clean the water port on the mower deck. Hook up a pressure washer and blast away.
I stumbled onto this channel yesterday (for VW/Audi reasons) and thought this was a well edited video:
He calls that a 2017 but in the US market that newer body style leaf was 2018+.
I would not recommend DIY HV repairs without the proper training, equipment and PPE however once that pack is out of the vehicle, with the modules separated into lower voltage segments, the diagnosis path is not extremely difficult. I've seen plenty of off-grid energy generation and storage setups for homes that were more complex than that.
There aren't very many independent repair facilities get into HV repairs in my local area however repairs like that will be far more cost effective for the vehicle owner as that changes.

I wonder how long it will be before a YouTubers video on repairing HV batteries is used in the inquest into their immolation?

The potential for thermal run-away and fires in big battery packs like that is a bit scary, but the electricity isn't. In another life before Ross-Tech, I've worked with stuff that ran higher voltages and currents than you'll find in any EV.

In a previous life I worked with 22kV supply and and switch gear and transformers and 3.3 kV big electric motors but i would not touch a 400V DC battery without the training and formal certificates and official manuals

Uwe and I played with 100KVdc... Not really... we stayed away from that part of the system if we could. Although there is the time I got zapped by a residual static charge on one. I'm still here! Guess I am a lucky guy.

As a kid, back on the other side of the pond, I distictly recall "zapping" myself on the apartment 220v plug, numerous times.
It took me a few times of this happening to figure out, as a ~5-6 year old, that plugging in the xmas tree light in the dark, into an extension cord that was already live, by "feeling" the plug prongs with my fingers as I tried to guide them into the female receptacle, was NOT the right way to do it.
Additionally, I also (but only once), found something my dad had which resembled a home-made test light.... from the little that I recall, it was a lightbulb with two wires attached to it... my kid brain told me that I should plug said wires into a wall receptacle to see if this thing lights up..... well, I did just that.... but I don't recall if the bulb lit up or not!

I woke up in a closet that was directly across the hallway from the wall outlet, with the closet bi-fold doors laying on top of me all broken.... I didn't feel anything, but I sure went flying!

I was blown on my back.. the wind knocked out of me.. totally conscious and wondering, was this it? Felt like I laid there a long long time. Reality was it was likely less than a minute before my lungs said, "Ok. Breathe!"
This was all caused by a failure in the safety system and lazy welders who thought it would be cool to throw their spent rods in the high voltage insulator hopper. I thought the safety system had grounded the system. I was flipping the rods out of the hopper with a 3 foot long stick - likely that stick saved my life by making the voltage craw up the 3 foot long surface. The voltage that reached me was probably far less than what was on the HV feed.
Lessons learned.

My father was was an electrician and then graduate electrical engineer who built, designed and ultimately managed a very very large HV DC electrical network powering a suburban railway system.
On weekends he would go and inspect a few of the many substations powering the 600V DC network and take me along when I was about 10 years old. The first thing i was taught was keep my hands behind my back and don't touch anything
By 17 at the end of high school I knew more than most electricians and electrical engineers and was alive and had learned how to avoid even the most obscure electrical shock and arc burn risks. Most people these days would not even know what a mercury arc rectifier if they saw it, is let alone know what happens if the glass bulb thats about 1.5 metres in diameter for a 1000 amp 600V one fails..... The answer is run as fast as you can !
I studied mechanical engineering at University and then chemical engineering when I was working as I always wanted to learn something new. But I always kept my hands behind my back (and my mouth shut unless asking a question) until I knew exactly what was going on

I picked up another tesla... I had the Vw Atlas for almost 6 years. The warranty was set to expire in January , so i was planning on ditching it soon. The EV tax credit was recently announced to be expiring in September, so if i wanted a new car , i had to do it now.
2026 Model Y (juniper)
This is the first time in 20 years that i'm VW free. Its kinda weird.
Shortly after buying the model Y , my wife learned she was pregnant with our 4th. Over the weekend, Zoey was born and a day later I traded the Y in on a 2022 model X :
Feature wise, it's very similar to the Y. The X feels like a more refined Y, even though there's a four-year gap between them.
Negatives:
It was expensive new (MSRP was around 136k on this specific car). Used, it was still expensive (cheaper than adding a 3rd car in the mix). It has higher mileage than i would like, with some wear on body panels. And the worst part it has a yoke.
I plan to retrofit a proper wheel later this year.
Overall, the car is awesome and I'm able to fit my entire family comfortably.
Being a fully loaded used car, I expect it to break. Tesla has a 1 yr/10k mile warranty, with the option to buy the extended warranty as a monthly subscription. Battery/motor warranty is good until 2030 , so i think we're fine.
