They do. Cops in America just want to jerk you around. People elect to participate because refusing usually means being detained and taken for chemical testing. Breathalyzers and roadside sobriety field tests dont work consistently and can be bypassed easily.
Yeah, there can be pedestrians and bikes where I live. With these new e-scooters and ebikes, they can appear pretty fast snd silently, and aren’t always in full control of their ride when going fast and don’t always obey the traffic rules. I don’t want to confuse them.
