Well, not necessarily. A bike that’s got a full carbon frame also absorbs shock and vibration from the road better. This means you can ride longer distances without getting fatigued in places like your wrists or ass. Longer rides = more exercise.
But once you have a carbon frame, chasing grams on other components gets to be a bit silly.
In my experience in an EU country, sufficient ID was also provided freely by the government (eg a social security card).
This is not something in the US that is free. ID must also be a photo ID. So let’s say you have a job where you work 7 days a week and take the bus because you don’t have a driver’s license. To get sufficient ID you must then: take unpaid time off of work, get to an office that issues ID, pay like $20 for such an ID… All to have the opportunity to exercise the right to vote.
This is both a tax and an unreasonable burden, effectively disenfranchising millions of poor people.
This is solvable though, if the government issues free IDs and sets something up to facilitate people getting their photos taken. However that would never be executed effectively, nor would people support paying the costs.
