@Pionir @ryansingel @AGTMADCAT > how is the expense for a new thing a problem when the cheaper things still exist and remain an option?
This assumes you already had the prior thing and had the opportunity to use it. I did specifically mention two cases where its use would've been impossible and the opportunity cost of improving one's situation might be prohibitive, such that all available choices are worse.
I'm quite glad that we didn't find some way to screw up our urban design enough to *need* helicopters or have much reasonable use for them.

Which already requires both monetary and physical ability to buy & use a car (considering how awful bus service is in much of USA, do you really think people are using it because they realistically have a choice?). There are several motor and neurological issues which prevent that (safely and/or legally) but not the use of a pedelec.
