They use drum brakes because drum brakes are protected better from the environment while brake discs are not and will quickly get covered in rust and dirt when not used for awhile and then be less effective when they are actually needed for an emergency braking situation. We only ever really went to disc brakes because they were slightly cheaper and easier to manufacture and since racing vehicles used disc brakes (be…

Seems like EV manufacturers should set their cars to use the friction brakes for the first few stops of each trip, both to clean off the rust & dirt, and also to test whether they still work.

I always assumed EVs use regenerative braking as much as possible on their own.

They do. But if you brake too agressively, they switch to friction brakes. It pays off to avoid this: more mileage, marginally lower charging expense, lower cost on brake maintenance and fewer complaints from passengers.

You have a weird dream of how people should use transportation. People like what they like. They like individual cars with 4 wheels. They don't want to share transportation with random people.

Pretty sure he's sarcastically talking about trains existing

We could also try to fix the anti-intellectual culture instead of just griping about it and/or retreating. It didn't emerge out of thin air, it emerged as a reaction to a mostly-accurate sense among non-intellectuals (i.e., the people who make most of the world actually work) of being constantly condescended to by the intellectual class. What we need isn't to go all prepper for some kind of dark age, what we need is…

We are fundamentally at a loss here because of the dynamics of propaganda. Simply put more money is spent misinforming than informing and since this will always be the case due the the powerful incentives of population control, there will always be some degree of idiocracy happening. Short of probably redistributing all resources equally and eliminating the money and economic system we have that lead to these incenti…

I think some research group did measurements of the AQI in the TTC stations and found the average air quality in the winter was actually comparable with the smog in LA or Beijing.

and people still look at me funny when I wear a mask in there I wonder what platform doors will do: the stations depend on piston effect for ventilation, but walling off the tube from the station might keep it more in the tube?
