Having an easily swappable battery returns some power to the user.
Or phones with USB-C.
I suspect this will be a good thing to force, but I don't know for sure.
Yes, making seatbelts mandatory was also a weird decision.
As an example of public policy it had significant impact on death, injury, medical costs, etc.
Road Traffic Accidents before and after Seatbelt Legislation-Study in a District General Hospital (1990)
Injuries among samples of car accident cases attending the Accident & Emergency (A & E) department of a District General Hospital (DGH) in the year before and after the introduction of seat belt legislation were classified applying the Abbreviated Injury Scale using information recorded in the patient case notes.
Those who died or did not attend an A & E department were not included in the sampling frame.
The number of those who escaped injury increased by 40% and those with mild and moderate injuries decreased by 35% after seatbelt legislation. There was a significant reduction in soft tissue injuries to the head. Only whiplash injuries to the neck showed a significant increase.
( ^ One of many before/after studies that highlight difference made by seatbelt legislation )
However people who don't want to wear seatbelts generally only endanger themselves. So why force them against their will?
The downsides to have seat belts usage not mandatory outside of reducing deaths/injuries. A few that comes to mind:
1. Parents don't wear them -> kids don't wear them 2. Friends don't wear them -> peer pressure not to wear them 3. Accident happens -> body flies out the window (risk of hitting someone, makes a mess to clean up) 4. Accident happens, person survive but is injured and is now a cost to society
Upsides (I worked with someone who refused to wear it and told me something like that):
1. Anecdote about someone that was wearing one and got into an accident and the seat belt somehow prevented them to escape the burning car and they died 2. It's less comfortable 3. Makes me feel alive (freedom)
He would only falsely wearing it when there was suspected police presence.
In reality, the worse an accident is (deaths, injuries) the longer and more difficult the clean up process is .. increasing the time that normal traffic flow is impacted and increasing the danger to all those attending who are exposed to potential (and common place) cascading disasters.
The deaths and injuries impact the local health response services - raising costs, demand for resources, and impacting triage decisions (fewer injured non seatbelt wearing idiots to look after, more free resources to devote to other patients).
However people who don't want to wear seatbelts generally only endanger themselves. So why force them against their will?
If the seatbelt saves your life from an accident in which you were at fault, it is easier to prosecute and extract compensation from the living than from the dead.
Additionally if it was optional people would forget to do it more often even if they don't consciously choose to risk their lives for no reason.
BTW they are not only endangering themselves - they also endanger their kids.
