Just came back from Austin (way smaller than Dallas) and it was during a large event weekend (F1 weekend). We used the electric scooters pretty much the entire weekend to get around the city, it was really good, much faster and efficient than taking an Uber/Lyft or driving. Most of the larger streets had a bike only lane and we never felt unsafe (my 70yo dad was riding with me on another scooter). Overall, I think that when combined with a good planning strategy from the city these types of micro transport could be something really good. I still think that good public transportation should be the goal here, but that requires way more infrastructure investment, and electric scooters or bikes could be the next best trade off.
