Garbage trucks cruise at a certain pace. They hardly ever stop and go, for good reason: fuel efficiency, wear and tear, and just general work efficiency. The drivers jump on and off and back onto the truck. Have you ever watched a garbage truck squad in action?
Where I live, the trash collection trucks have a hydralic mechanism on the side that grabs a trash can, pulls it up, and dumps it over the top. And to to do that, it comes to a full stop.
The system you are describing sounds dangerous and uses far too much labor. Maybe your city has a trash collectors union with too much power.
I'm talking about NYC...it has been working well for the last 200 years with little in the way of change. I'd say the city knows exactly what it is doing...
Having the collectors use a robotic arm rather than just a fleshy garbage man for dumping the bin..that's only something you see in "new cities" that have no clue on how to do efficient garbage collection. Now..."YO!! get offa my steps you stoopidabass!! go backtoodah burbs ya yankee dandee sass platoon!!" ;-)
