OK, you obviously have no, or very little, experience flying single
pilot IFR. There are times when things get very busy and the cross

Little. Anyway, if you can't do the cross checks, then you're not safe.
If single pilot IFR means that the workload is too high to regularly do
the cross checks, then it's debatable whether single pilot IFR in IMC
should be allowed at all.
