I don't.How would you then propose they should do it in order to have them race as one team?
Have a men's Team Time Trial; have a women's Team Time Trial. On today's evidence, the best national teams for each are Italy and Netherlands, but riders in neither team have gold medals to show for it.
I see no sporting reason to combine them. A sportsperson's results in a team event should be dependent on those meaningfully linked to them in a team effort, not only to those who do a different effort in the same kit, but otherwise, both in competition and training, entirely unrelated to them.
