I am wondering what the minimal monthly data plan cost would be to have this working continuously on your street. In a suburb, surely 20 phones would be enough, no? At $30/ month maybe somewhere between 500 and 600 per month?

The device itself should be able to discern the mode of transportation, no?
Pretty easy to train some ML network to differentiate between transport modes, assuming the device has a accelerometer / gyroscope / whatever.
I did one project in school (albeit a simple SVM based model) to classify walking vs running (and so on) and ambiguity was still there. Stationary vs. Walking was easy to draw a hyper plane in between, not Running.
I still find it a difficult problem to get into, after 5 years. Perhaps ANN models might work better? Although my heart is still at Hidden MM states...
I don't think enough people use Google maps in my area for it to be consistent much of the time.
Lots of random (not on map) or way out of date slowdows. The reporting feature doesn't seem to do much.
Granted otherwise it is a great app, and I don't pretend to have the solutions to the wonkyness, just wonky at times when it comes to identifying traffic issues.
I wonder whether Google Maps takes into account the various ways of transportation, such as bicycles, public transports, or electric cars driving on the bus lines.
I'm stunned how fast Google Maps detects traffic jams. I assume all those smartphones are running car navigation and as traffic detection works by trusting the clients I fear there's no chance to avoid this kind of exploit. Nevertheless it would be interesting to know what's the ratio of correct / malicious clients to fool the system. That migt highly depend on whether Google implemented any detection of faulty clien…
You can probably avoid it by more accuracy somehow. If the road is just for 1 car width, and there are 50 cars in the same radius (because all are inside the cart), it’s an impossible scenario. I think gps accuracy is something like 3 meters, which is about one car length.

How did you fix that? I’ve been wondering how google and the others differentiate between cars on the free vs express lanes.

It's easier with historical data since you know the full trip, but even real-time should be doable.

Just do it on wifi. With a bit of spoofing you could "move" all the phones up and down the street while they're in your basement.
I might be getting older but "hack" these days seems to just mean "go to work" or even "go to work on the weekend".

Yes, if you look in your Google Maps timeline it can even often guess which mode of transportation you used.
