It is much more cost effective and environmentally friendly to tear down parking garages and replace them with new construction.

For 1 - sure yea, I sorta doubt developers are going to voluntarily go below 1 space/unit in any sort of world because the value of the property takes a steep dive - but removing any commercial unit parking requirements or higher requirements for larger residential units makes sense. I think 2 is great - assuming exceptions are made to support park & ride demand. 4... Eh, EV is going to need to solve this through market forces so I think we can entirely ignore this (though I would love to see a lot more EVs I think this is point is entirely tangential to the main discussion) Lastly for 5 - nope. Every building ever has managed to sort this out naturally without regulation... leave this up to the market.

LA desperately needs for transit extensions.

The first application to build this building (replacing a small family home on a relatively large plot) was rejected for having too few parking spaces. Policy at the time assumed housing needs space for cars, if you don't build space for cars they litter the streets so each home must have 1 space or more for larger homes.

But the last application (ie the one they actually built) was only accepted after reducing the number of spaces, because by then policy had changed to dissuade people from owning more cars. They'll park them on the street anyway (and they do) so giving them more spaces just encourages owning even more cars in a congested city.

Here in DC, we have "bike lockers" at the Metro transit stations so you can park your bike there and take the train into the city. However, these lockers aren't cheap, and there aren't many of them, and they're completely enclosed so they take up a fair amount of space. By contrast, in Germany you'll find many hundreds of bikes just lined up and parked outside the S-bahn station, without people having to pay a hefty rental fee.

That´s everywhere. I was told that in Austria the only major petty theft is bike theft (in one of the most secure countries in the world).

I don´t even need to mention how prevalent it is in my country Uruguay (which tries to encourage bike use).

In this case, if the government authorises the construction of more than 300 parking spaces, unacceptable congestion will result.

I do think that 1 would need to be tempered with some handicap minimum though.
