  • Which btw that program isn’t doing too well. It’s a huge cost right now, compared to more traditional public transit. And imagine that this is with regular “cheap” vans rather than more expensive vehicles. These also seem to be a small step better than Personal vehicles as I hear most rides are solo rides (which is not exactly the aim). What is great about micro is they support bikes, and people with disabilities to help reach the last mile in their trip.


  • Most of those can addressed by busses too actually.

    Train has fewer stops meaning train reaches the destination faster

    Bus Rapid Transit (BRT) or any bus line can have less stop for this reason. To expand on BRT routes, they can be dedicated lanes for busses, with right of way. They can be specific only for busses, and cars not allowed to use it ever or also mixed usage where certain rush hours are for bus use only but outside those hours can be used by other vehicles.

    Train has ultimate right-of-way, and doesn’t have to stop for pedestrians on the tracks, red lights, or other things

    This can also be done with BRT routes.

    trains in some cities, go under waterways meaning more direct routes than busses

    BRT as well.

    there’s more space inside trains and usually more choice of seats. Standing is also an option which isn’t allowed on most busses

    Busses can absolutely support this. Paris has more open busses to allow more people standing or people with disabilities.

    acceleration and deceleration are more predictable and comfortable

    With dedicated BRT lanes, I believe that can also be done considering there’s only bus stops that need to be slowed down on.

    Nearly all metro light rail trains are powered by electricity, while many city busses remain diesel

    I know technically electric busses are possible, but I’m not certain how feasible this is.

    My understanding is that BRT routes are cheaper and faster to setup than trains, and can be upgraded to trains. I’m not saying BRT is better than light or heavy rail, but that should be a more common path for mass transit that is not utilized in the US.





  • All these people saying its 135 are making big assumptions that I think is incorrect. There’s one triangle (the left one) that has the angles 40, 60, 80. The 80 degrees is calculated based on the other angles. What’s very important is the fact that these triangles appear to have a shared 90 degree corner, but that is not the case based on what we just calculated. This means the image is not to scale and we must not make any visual assumptions. So that means we can’t figure out the angles of the right triangle since we only have information of 1 angle (the other can’t be figured out since we can’t assume its actually aligned at the bottom since the graph is now obviously not to scale).

    Someone correct me if I’m wrong.


  • Can you clarify what you mean? this doesn’t make sense to me. There isn’t an “outer” triangle. There’s one triangle (the left one) that has the angles 40, 60, 80. Both triangles are misleadingly drawn as they appear to be aligned at the bottom but they’re not (left triangle’s non-displayed angle is 80, not 90 degrees). So that means we can’t figure out the angles of the right triangle since we only have information of 1 angle (the other can’t be figured out since we can’t assume its actually aligned at the bottom since the graph is now obviously not to scale).









    • Not everyone has the budget to openly spend 20K plus on a new vehicle, which means lower demand
    • Since not everyone will just buy a new car, companies need to make as much money per unit sold which means luxury cars make more sense These points together should make sense. They are marketing to people that have a lot of disposable income. If they have a lot of disposable income, they probably want a luxurious car. People with 200k+ annual salaries want to keep up with the Johnses so a 20k EV car they can easily afford doesn’t look as cool compared to their neighbor’s 80k+ car. So they want a 80k+ car with all the bells and whistles.

    The reason we stop China is not related to supply and demand so much as stopping companies that China has given unfair advantages to. If BYD was making cars without signifcant Chinese subsidies, then yes I would be bothered by these tariffs as well.






  • I mean the tech is still new as well as the point that SSJMarx mentioned. To add to the list of reasons to make expensive version of cars first:

    • New tech is more expensive usually
    • Not everyone has the budget to openly spend 20K plus on a new vehicle, which means lower demand
    • Since not everyone will just buy a new car, companies need to make as much money per unit sold which means luxury cars make more sense
    • additionally lowering demand is the fact that not everyone wants an EV or feels comfortable driving them (due to its different fueling method)

    I do expect that over time manufactures will begin to release cheaper EVs over time that are aimed for average consumers.
