A pedestrian may illegally have entered a road, but still have right-of-way, and self driving cars will need to account for that.
However, protesting self driving cars will not change whether walking in the street is legal, since it already is not.
Therefore, whether you do so and get fined by police is entirely up to their discretion, which could change at any time for any reason.
If you want it to be legal, protest the illegality, not the car company.
