I kinda' liked the Vespas, they made me smile. If there can be hovering trains and rocket backpacks, why not these too? The chase was a little tame, though.
Overall, I'm enjoying the series so far, though, and think (as others have noted) that old Boba is a more interesting character here than he is in the films, where his character is little more than a cypher. He's seen the Empire fall at the hands of the more reasonable, but no less kick-ass, rebels - so maybe he's taking a leaf out of their book as well as slowing down a bit due to experience, age, and physical deterioration. I wouldn't be surprised if he teams up with the Mandalorian, or a Jedi, at some stage - after all, even Vader came back over to the light side in the end.
*Edit* Bullitt wasn't a very good film - except for that car chase.
