I support the /62 recommended for cellular handset broadband, rather 
than /64 recommended.

Also, I see Philipp mentions an assignment /64-/80 (recommended and 
minimal) for Enterprise client device.  This Enterprise client device is 
probably inline with ChromeOS and DHCPv6-PD and this pd-per-device 
draft.  I am not sure whether /64-/80 work for this pd-per-device 
draft.  I doubt it does, because of the draft saying 'shorter' without 
saying of what.

Finally, if I suggest an addition line in the table, I would suggest one 
for the automotive industry, for cars in networks.

It should be:

Recommended /60               Minimal /62

Remark that this prefix could be allocated to a car by a cellular 
network, by satcom (e.g. starlink) or by a WiFi network. Sometimes it 
can be allocated by an Enterprise WiFi network in a garage.
