The technology saves weight and installation space by eliminating the requirement for hydraulics Exactly how much weight/space is being saved here? In an EV with a heavy battery, my guess is not a very significant amount. This looks like an example of ignoring the forest to focus on a tree.

"Not a very significant amount" nominally, but multiplied across millions of cars driving millions of miles it adds up very fast.

  Most people could save more weight by simply cleaning out their trunk.

Bosch is famous for being anti-right to repair. To work on their E-Bikes you need a certification and a special tool set. Probably the primary feature of these brake systems for Bosch is locking end users into Bosch certified maintainers and parts.

  This seems to be a German speciality. It costs $700 to change a dead battery on some Mercedes cars because the onboard computer has to be reset using special electronic tools. This "screw the customer" approach is the road to self destruction. Just ask Volkswagen.

    The German automakers avoid competing with each other in multiple areas, including colluding to limit the size and dispense rate of DEF tanks and collectively claiming to lawmakers that certain emissions regulations would be impractical. I can't find a citation, but I recall seeing an estimate that the German automaker cartel increased prices on the order of $10k per vehicle. I had also read that there is a similar cartel among the automotive suppliers, none of whom seem capable of making a windshield wiper set that isn't hundreds of dollars, or a vehicle lighting below multiple thousands of dollars. “People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices.” -- Adam Smith https://www.spiegel.de/international/germany/the-cartel-collusion-between-germany-s-biggest-carmakers-a-1159471.html https://www.spiegel.de/international/germany/the-cartel-coll...

    I have a couple cars, some german. It absolutely does not cost $700 to change a dead battery any more that it costs $100 for a bottle of water. The cost of goods is cheap. You do need to tell the computer it is a new battery, since it adjusts charging voltages based on battery age, and if you don't do this it may overcharge the battery. Talking to the onboard computer is free beyond the initial equipment and it isn't even locked or anything, tools that can do this can be had for cheap, connect to your phone via bluetooth etc.

      Resetting the BMS via a diagnostic tool is not really a thing on newer Mercedes, but I could definitely see a dealer additionally charging as much as the battery costs to reset it on an older model that does need it. You can buy dongles and do it yourself, but not everyone is willing to mess with coding their own vehicle.

You save the plumbing to near the pedal box and maybe the plunger to the master cylinder... and that's it? Not my world, but I don't get it - with throttle by wire you can do fun dynamic/nonlinear response, cut throttle when you don't have traction etc. With this thing, all the clever things are already done by the ABS/ESC unit, so removing the physical connection really only frees up like like 50 cm of a hydraulic piping. Would love to hear an automotive engineer's take on this to be honest.

  The piping in this case has a diameter of about 3mm. I'm not even sure you could measure the weight savings on a vehicle by removing it.
