have to say i've never paid to use either the m6 or the severn bridge when I was coach driving. I always planned my rest stop for Norton Caines services where coaches got a free voucher to use the m6 toll if we stopped. and as for the severn bridge I just never went that route into south wales it was just as quick to take the scenic route or the M50.
Only had to cross the humber bridge once and that cost me over £12.00
(good job I got the money back)
as for the hov lanes they do have these on certain busy stretches of motorway up and down the country nearest one to here is the m62 just before bradford where they have the 2+ lane.
