How do we get mobility that creates more value than it destroys?
Mobility is the potential for movement. That the road is clear if I want to drive. That there is a bus or other public transport running on schedule. That there are safe sidewalks and bike lanes.

Two-thirds of California's power comes from clean energy.
For 9 in 10 days so far this year, we were 100% powered for some part of the day by clean energy.
The Golden State has become the world's fourth-largest economy because of our climate leadership, not in spite of it.

A great reason to be a transit service planner instead of a transit infrastructure planner is that we service planners deal mostly in cost numbers that are easy to explain.
Unfortunately, they tend to be tiny numbers. The big money goes into rounding errors and contingencies for infrastructure.

It's impressive how contemporary projects' budgeting practices in Canada are made of very thin actual analytical estimates based on quantities and unit prices on top of which there is an entire enormous castle of random percentages of percentages of percentages which are suspiciously multiples of 5.
