Severe heat, heavy snow, or torrential rain can make driving a car unsafe as well. Individuals with certain disabilities, chronic health conditions, or a plethora of age may also find driving impossible. For those with "trip-chaining" needs, extra time required for parking cars can be prohibitive. Old people don't like traffic and can escape and run away so fast you have to drive them back? And you're seriously including the idea that car theft is not a concern? These are some tortured arguments.
The correct argument here is "if bicycles become the dominant transportation mode, then the government will absolutely mandate kill switches for them too." "Bicycles don't have software" hasn't been true for years. E-bikes and wireless deraillers have been around a long time.
