Some drivers rely too much on one pedal driving only to brake in a panic when they realize it will not stop the car in time. This creates a very uncertain environment for other participants in traffic and I can't tell you how many times I had to step back from a crossing because a driver clearly misjudged the breaking distance of their car using regen braking. It creates a bit of complacency where the expectation is that "the car will take care of it" and one pedal driving does not give the same control over braking as it does over acceleration (or as the regular brake pedal does).
Other drivers assume max regen settings will bring max benefits and end up taking more out of the battery to accelerate only to get far less back (regen braking is ~70% efficient in any EV) when the car regen-brakes, when braking was not really required. Many times coasting is far more efficient than regenerating regardless of what pedals you're using.
Last but not least, all regenerative braking systems are combined with hydraulic braking at low speeds because the torque applied to decelerate is not enough in any of them. So at low speeds the car will actually combine it with friction braking and eventually not regen at all. Take the Zoe where there's no regen at all below 15km/h (9 mph). Emergency braking from high speed is the same. City driving will see a lot of those situations.
So whether you realize it or not, when you are coming to a standstill you use the hydraulic brakes. There may be options to break at low speed with no friction at all but they will not be called regenerative because they will inevitably use energy to do it.
