Summon’s issues? Nope. Do you happen to have a link? Plenty experts say that L5 autonomy will probably never be possible. So, Level 4 at best? Or switch to manual mode when you want to enter a city and pass the city’s outer markers, or something? Btw, nobody has made the link yet: between the 81% rise in ped fatalities in SUV-related accidents, according to the IIHS (Over the period 2008–2018), and using SUVs and big MPVs for driverless experiments. The NHTSA should look into this, IMO.
