Exactly my thoughts. The hearse was driving from Lancing to Worthing at such a pace, I nearly lost touch with it.
The Henfield one did drive from the church & up the High Street at walking pace, but once clear, drove at normal speed.
Ive been to two funerals in the last couple of years where the church service has been followed by cremation at Worthing. My aunts in Lancing, and a cousin in Henfield. Both times we were overtaken by loads of vehicles when on dual carriageway.
