here are some examples we found in our initial survey, some may no longer be current:

@jean-populus if you can answer the questions above, maybe @karcass can see if these scenarios are possible now in Policy with some examples?
The examples were pulled from publicly available policies in 2019 so I'm not sure how accurate they still are and I don't have any further details other than what's been described.
It feels to me like we could have advanced rules where we could define a relationship between two sub-rules. For example, "set the ratio of rule1: rule2 to minimum X". This could then also work for distribution by %.

- Even trickier since this involves two counts: trips and devices
- Using a Metrics API could make this easier. However, some metrics may be difficult to support. What are the simplest things to be measured vs complex
- Should we restrict Policy to rules that can be calculated via Metrics? But don’t want to replicate Metrics in policy.
- In order of complexity: Could 1) add things into policy 2) add well established metrics 3) dynamic metrics calculations
- Jean offered to share what Populus has been tracking policy-wise pulled from all cities

@avatarneil and @karcass Could you take a look at this, like you mentioned on the WG call last week? Thank you.
Posting an update from presentation MDS Policy Extensions 15 July 2021
FYI I'd be in favor of deferring this for now as Utilization is not currently a part of metrics and seems like we should have a larger convo about metrics & policy.
Is your feature request related to a problem? Please describe.
A few cities have policies around minimum utilization (# rides / # vehicles) but this isn't currently possible to convey using the rule_types which are: count, time, speed, rate, user. In this case we need two different counts - one for trips and one for total vehicles - and the policy is a ratio of the two counts. Cities also would like to specify a time period over which to measure - for example, is it a daily min or a 7 day average min?
