I see this argument kind of like moving into an area that has a MX track and wanting them to be quiet. Or, moving right next to a gun range and wanting the gun range to shut down because it isn't safe. It doesn't matter if there is another option for them or not...at least to them it doesn't.

If you don't like people driving on beaches, go to a section of the beach that isn't accessible by car. It's not like sections like that aren't available in the general area.

As far as safety is concerned, again, it is the individual's choice. If I don't want to be hit by a car, then I should stay in a safe environment. I shouldn't expect to be able to go wherever I want and make the people who already using it adapt to my ideals.
