To each their own. I like my TM3 and enjoy regenerative braking but there really is not reason to use a blended braking system which keeps with the current petrol car model of, use the brake pedal to slow down. It also may be safer since your foot will be over the brake when needed.
Chevrolet used this on the Volt for normal driving, you press the brake pedal and it decides how much hydraulic brakes you need over what regeneration can provide. Audi is going this route too. What makes it even better is they can totally mask the loss of regeneration in cold weather which can be disconcerting.
If anything I think Tesla should make it an option, the loss of regen braking even when the pack is only saturated to 40F is bad enough and just useless below freezing. They can do wonders with OTA so there is no reason to not offer all options, low to regeneration, high regeneration, maximum, and blended.
Again, blended doesn't mean it uses the disc brakes, only that it can when it has too and this is safer than relying on one pedal driving.
- m_mueller 8y agoYour point about safety raises an idea: Why not do the inverse? Your driver assist tells the car how fast it can drive (GPS, signage), break pedal as well as a configurable level of assistance tells it how much to stop. Steering is still mine, and I won't give it up until full autonomous cars with zero driver responsibility are mass produceable.
- fastball 8y agoBecause I want to drive over the speed limit.
- m_mueller 8y agoI'm not saying take away the gas pedal - it could still be there as a 'boost' pedal, intended for overtaking for example.
- fastball 8y agoMy car already does this with radar-informed cruise control, except it doesn't force a certain speed on the driver. You just set it like normal cruise control.
- m_mueller 8y agoBut doesn't cruise-control ususally disengage when you hit the breaks? This is only half the idea of single-pedal driving on the break pedal.
- CydeWeys 8y agoThere's a lot more to how fast you can drive than GPS and signage. There's also weather, road conditions, if there's parked cars hurting visibility along the road, whether there's pedestrians near the edge of the road (especially children who might dart out quickly), etc. You have to slow down to turn, too. I can't imagine a situation in which you could let speed be outside the driver's control entirely.
- m_mueller 8y agoYes, therefore you either a) break yourself on turns, pedestrians waiting, even red light etc. or b) choose to let driver assist take over some of these tasks from you the whole idea is that instead of doing one-pedal driving on the accelerator it's safer to do one-pedal on the break.
- zaroth 8y agoIt would be great as an option! I would still keep it as separate functions on separate pedals. Because I don’t want to use the pads, I have to drive a bit differently when less regen is available. I really like single pedal driving in the first place (see note above about lane changes and such) and I would never want to the pads actuating just from lifting the accelerator. The only enhancement I would be happy with is full regen under all operating conditions :-)
- saalweachter 8y agoThe Volt (and probably Bolt) offer a number of options. In 'D', releasing the accelerator coasts; in 'L', it decelerates, presumably subject to the same limitations as the Tesla. There is also a paddle on the steering wheel which activates regenerative deceleration independent of the brakes. This does not completely stop the car, and has a longer braking distance. So with the car in 'D' the controls become: press accelerator, go, release accelerator, coast, press paddle, slow down, press brake, stop.
- steve_musk 8y agoDon’t Tesla’s have the same option? You can set regen to low I believe.

- zerohp 8y agoThe Volt also has a hand operated brake paddle behind the steering wheel to activate regenerative braking without engaging hydraulic braking. It's a very nice feature.
- therein 8y agoDoes that make the brake lights turn on? I would imagine it should because you're slowing down nonetheless.
- ams6110 8y agoDownshifting a manual transmission to slow down does not activate the brake lights, so not sure this would need to.
- greglindahl 8y agoDepends on your goal. If you want to rules-lawyer, then sure, no need to turn on the brake lights. If your goal is to avoid rear-end collisions, then having brake lights illuminate no matter why the car is decelerating is a good thing.
- CarVac 8y agoI believe that on at least some electric cars there's a particular deceleration threshold above which it'll turn on the brake lights.
- greglindahl 8y agoTeslas definitely turn on the brake lights in some circumstances for regenerative braking.
- cmrdporcupine 8y agoMy understanding is that in Gen 1 Volt, no. In Gen 2, yes, and also when you let off the accelerator quickly in 'L' (higher regen) mode, if your deceleration is beyond a certain point the brake lights engage.
- gameswithgo 8y agoit is an option. you can turn if off, or at least way way down in the settings
