The hardest part of teaching is it's impossible to remember what it was like to not already know something. You can't un-know it so get back your previous perspective. So, you forget all the things you take as known.

This is the problem I find with the 3blue1brown videos. They're pretty but I never get any understand from them. To people who already know they nod and see all the concepts they are already familiar with shown in a neat way but to some (like me) they don't generally get me to understand. Too many pre-reqs or someting

I want trains and public transportation. Have lived 18 years in cities that had good public transportation. The kind where 95% of the population uses it often, many daily. Had friends who owned cars and they still mostly used public transportation. The cars were something for weekend trips but those friends were the exception.

Unfortunately to get to that level in California means adding 60-80 lines with 20 to 40 stops each, having a train every 5 minutes, having express trains that skip stations, having the trains go fast, having busses every 10 minutes, keeping all of it clean and safe.

We'll never get that and so people will keep asking for more freeways but the train can be so much nicer.

Also, a common excuse is population density but....

Switzerland has tons of trains, is a 3x the size of the bay area with the same population

Switzerland ~8 million people

Bay Area ~8 million people

Switzerland size: 41000 sqkm

Bay Area size: 18000 sqkm

Switzerland train tracks: 5200 km

Bay Area train tracks: ??? (I think It's under 500 km so 1/10)

Traveling on a train can be great! You get more space than a plane, you can work, relax, eat, etc... Vs a car where you mostly have to spend all your time concentrating on driving.
