We lived in a big town when Püppy was young - - so:
watching people getting in their cars and getting out their cars
watching people loading their cars
watching people driving inside/outside their garage (and watch till the electric gate got shut really completely)
- - all this preferring lying comfortable on the pavement, me standing next to her
watching people getting on/off the bus
watching traffic at big crossings
...not mentioning wanting to get in cars with open doors...or houses with open doors...
Or we are walking and he sees strangers coming on the opposite side. He sits and waits to see if they pet him...
Problem: he's almost 7 months and super cute... so he succeeds 99% of the time!
