I don't believe Jeremy Bamber went via the sea wall.
I don't believe the sea wall route was feasible.
Bamber didn't know the route
Fields and bad terrain
Too dark. Unable to see.
Route surrounded by shrubbery.
Goes through three farms
Populated sea wall ( de'ath).
It's my belief
Will address each point.
You have the right to believe he drove.
Bamber knew the route for years. Or could learn it.
Good terrain. Farm tracks around fields. Lots of sources supplied.
Good light. Lots of sources supplied.
No shrubbery.
Prosecution route goes through one farm - Wyke Farm. Another route available.
Bamber's cycle ride very remote. No one there at dark.
Your belief is your choice. But your stance that the prosecution route is a 'non starter' does you no credit.
