DVLA reminders

[Dave48]

You are still meant to get a paper reminder (V11) in the post. I would imagine not getting one isn't an excuse though.
"To drive or keep a vehicle on the road you will still need to get vehicle tax and DVLA will still send you a V11 or V85/1 renewal reminder when your vehicle tax is due to expire. This applies to all types of vehicles including those that are exempt from payment of vehicle tax or have a nil rate of Vehicle Excise Duty (VED)."

If the thinking behind abolition of paper discs was to save costs then why dont they send email reminder"VED due" to registered keeper to save more postage cost?
