That's interesting. It demonstrates that regenerative braking really works. The energy you expend going uphill, you mostly get back going downhill. The energy you expend speeding up, you mostly get back slowing down.
His tests were a round trip, so start and end altitude are the same.
And he kept a fixed speed on a freeway, so there wasn't much acceleration energy expenditure or energy loss into friction brakes.
You don't get drag or rolling resistance back, so that apparently dominates.
Those don't vary too much with load.
Looks like rolling resistance decreases with diameter [1]. So, is it from the increased drag from higher stance? Would lowering the car the same work better?
I think it's mostly from aerodynamics. Lowering the car could help but even just smaller rims, with the same overall diameter (rim + tire), can have a 15% impact on range. This Engineering Explained[1] video does an okay job with some of the math but he clarifies it well with a comment:
> CLARIFICATION! Why do bigger wheels mean worse efficiency, when the overall tire diameter remains the same? This comes down to aerodynamics. A 20" wheel will cause more of a disruption in airflow than an 18" wheel. That's why Tesla (and others) uses aero covers on their wheels (Car & Driver testing showed it gives about a 3% efficiency bonus at speed). The smaller the wheel, the more of the side profile of the wheel & tire is perfectly flat (the tire is flat, the wheel open: more tire = more flat area, less open area). Ideally, you'd have just a plain, solid sheet for the wheel, but obviously that's not idea for brake cooling. Wheel covers are today's common compromise as they have some airflow, but minimal.
> While drafting the fact sheet, we checked two headline policy ideas that the One Big, Beautiful, Bill introduced: the early sunset of the consumer EV credit and a new $250 annual EV fee. While the annual fee was dropped from the final legislation, the $7,500 consumer credit now ends September 30th.
> For the Equinox EV, these changes would cut its seven-year savings over the gasoline Equinox from about $9,000 to under $200. The Model Y also showed savings compared to its gasoline comparison under that less favorable scenario for EVs.
That link also factors in fuel savings which depends on where you live. I'd personally never save on an EV if it costs more upfront.
SCE will screw you nearly as hard. We are on a tiered usage which is the cheapest they offer and it's $0.32/kWh and even at that rate the EV isn't much cheaper than the non-hybrid I replaced. I'd need to switch to a ToU plan which would increase my other electricity costs.
Also for depreciation:
2020 Mazda 3 - sold $18k at dealer, originally $28k, 64% retained
2022 Kia EV6 - bought $25k, originally $55k-$7.5k federal, 53% retained
That's great to hear as a fellow Reverb G2 user. Starting with Windows 11 24h2 they dropped all Windows MR support. It looks like there's also a driver called "Oasis" now which restores functionality on Windows.
Yes, for a while there was no Windows support and they were extremely cheap, a great HMD for racing sims on Linux. The emergence of the Oasis driver has increased demand for them again but they're still a bargain.
I can't promise how effective it is but Google Pixel phones have a built in scam detection feature in their dialer app. It uses a local LLM that runs on device and analyzes the phone conversation. Here's their support doc: https://support.google.com/phoneapp/answer/15654065
It likely only works for US English phones, and of course if they get him onto other platforms like whatsapp or signal then it's no help. Sorry to hear you're dealing with that it's a big fear of mine as my parents age.
I remember watching a documentary about a man who would marry (multiple) women, then steal their money and leave.
one of the victims said she had doubted the ring he gave her was real, but he just scratched a mirror with it to prove it was real. Then she said "it was only later after he left that I found cz can also scratch glass"
Your link isn't exactly a white paper, here's a Subaru link that mentions radar: https://www.subaru.com/vehicle-info/articles/what-is-adaptiv...
