Ah, so we didn't get all the useful facts first time around, eh?
And now it seems you are pitching me against your own solicitor - just as well that I'm on the ball and know my stuff on employment law, then.
No, I've never heard of the situation that you describe.
I suspect that the employer will counter that it was a local arrangement between you and another employee, who happened to have the benefit of a company van. He/she came to an agreement with you to pick you up in the course of his journey to work.
Worth a try if you have no other way of maintaining employment, but I can't say which way it will go
