I confirm and that’s an unpleasant surprise. Already had to replace the rear rotors and pads on my Highlander… because of rust. They should add some “brake cleaning” mode to temporarily disable regenerative braking.

There’s been a few suggestions that drum brakes should make a come back, for EVs. They’re enclosed so they don’t get dirty, the inner face of drum will rust less than discs, fade is not an issue thanks to regen braking, and before they get too hot and fade drums will brake harder than disks (thanks to a higher pad surface area). And they’re enclosed so they also keep the brake dust inside the drum, making it easier t…

And, you can make much lighter and lower range electric cars without all those heavy batteries, and boost the range with diesel when needed. Very attractive in principle. Most cars are not using their full range all the time, for a lot of people a 50 mile range car would be more than enough 98% of the time, but that remaining 2% means that people end up buying 200 mile range cars instead. But then, do you end up remo…

I thought about PHEV but in the end went full EV simply because it seemed to me with two whole power trains that's 2x the components to go wrong/need maintenance.

This. This times 100x . Also, it’s not like each powertrain has an independent failure mode. If either break, your car is a brick until it’s fixed.

I am just excited because the more EVs mean fewer idiots in hot rods running without mufflers.

I think these will switch last and will found new opportunities to annoy you once switched.

Exactly. What people really hate are loud young people from lower class than them backgrounds. Civics with stupid exhausts are just an example implementation of that. They'll just find something else to hate if you remove that implementation.

Good to have more data points and evidence, but this seems extremely well established by now? Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.

The kids will find a way to be flagrantly annoying. Always has been always will be. Taking their fart can exhausts will be a minor bump in the road. It's not like EVs don't come factory equipped with tons of power to drive the kind of audio systems that people like you also hate.

Much better at what ? Do you have decent data for what it takes (CO2, child labour , cost of supply chain, ...) to make your Lithium based battery VS melting an ICE ? Same question for recycling ? Comparing only the lifecycles of products doesn't make any sense if you don't put in perspective creation & destruction and this is where the massive lie is, no EV constructor has ever been transparent about this because it's overall just way dirtier by no way cleaner !

Extracting rare metals from Africa, sending to China for transformation into batteries and back to US/EU for putting into an EV (that we cannot properly recycle yet) just cannot be cleaner than melting an ICE with processes that are 100+ years old and that can be done locally without the use of ships to make 3 roundabouts on earth.

Yeah established on a truncated view of reality !

Well there are new classes of idiots I see pretty frequently - a typical tesla driver going 90 in 120 region of highway without any reason, presumably saving last bits of battery (that has at least some rationale, if they do it due to ie fear then they should not be driving or having license). Over say 50km part of highway, maybe 2000 cars need to overtake such almost stationary object (to regular traffic which gener…

I think it's a hilarious example in how buyer demographics effect things. Every Tesla is a potential rocket ship if the driver wants it to be yet they're rarely if ever not driven circles around by laden work vans.

"Artificial engine sounds" is the next step in that evolution pipeline. Or just blast advertisements.

See the Ioniq 5 N. But those sounds are piped inside... not blasted to the neighbors...

which is the whole point of hybrids Part of the point, not the whole point. Regenerative breaking is absolutely a win; but there can also be a significant benefit from allowing the ICE to remain in the RPM "sweet spot" rather than moving around a larger range.

This is the thing with good hybrids. The "gas pedal" becomes a "I want to go faster/slower" pedal, its position has zero impact on the RPM. As an anecdote: A security company I know only buys Toyota Hybrids for their guards just because of that. They have a habit of driving cars like they stole them and normal ICE cars break down from that kind of abuse. Hybrids won't let you abuse them, they pick the RPM and you dea…

Do all Toyotas do that? I'm pretty sure that my dad's Corolla will rev the engine when I press the gas if the engine is already running.

I'm also surprised for the first few minutes when I drive it how little "engine braking" it has (my habit is from riding a big motorbike).

Was very concerned until I realized you were talking about kilometers and not miles. Otherwise, I'd hope the average driver would firce themselves to drive slower than 120mph out of some sense of fear, or at l…

Miles are bigger than kilometers so the guy doing 90 among traffic that wants to go 120 might actually be worse in miles because it's a larger speed differential.
