With experience in the past, I would strongly suggest that next time we cruise through any city with traffic lights. Is that we double up or take 2 lanes( if possible ) side by side when doing the speed limit anyways. Because at some point in time some may get stuck at the lights therefore some people may get lost if this happens. By doubling up, it cuts our line in half, with a better chance everyone could make the lights. Then we also have about 3-5 local people at different parts of the line incase of not able to keep up with car in front of you. Stagger the locals like e.g. Lead car(local), more cars, then Local car, more cars, then Local car, more cars, then Last car( Local).
Then if the line breaks up, next Local car takes the lead if necessary. and so forth. Try our best, that,s all and SAFELY. When a turn is approaching. signal early enough so everyone can ZIPPER together for the turn UNLESS its a double turning lane.
I've experience this enough that some get lost and are left out. I'm sure others have had this happened before too.
Otherwise like Brian had some do, Get the Glympse APP. It works quite well.
Just my two cents. No stepping on anyones toes here I hope.
