Told the guy straight that if this oik came looking for me they (Bridgestone) would be deeply embarrassed!Good result - he deserves it . You are probably already alert to it but take care to conceal/restrict any contact details when complaining.
I had an incident a few years ago where a similar idiot in a works car (with logo - IT company) severely tailgated me on a motorway and then cut me and several others up as we slowed on slip road and he repeatedly re-joined carriage way and cut back in. I was incensed and tried to ring company number when I got home but they had left so I emailed them. Received a grovelling apology from MD and assurance individual would be dealt with.
A number of days later I received a suspicious email with a reference to speeding and dangerous driving and an attachment which fortunately I didn't open. The other half was working for local constabulary at the time so she asked their IT Fraud people to have a look at it and attachment had virus implanted. They couldn't justify looking further but I made the MD aware of the amazing co-incidence.
For starters, I'd be ensuring that there would be postings that always appear above Bridgestone in Google.
