My new company asked me to sign a form if I wanted to use my car for company business. Looked at the form and noticed that it also had a "bicycle" option, so ticked that one instead, and signed. Not used the option yet. First chance, the customer's office was so close, walking was the most sensible option. Actually it was so close I could probably have had the conversation by yelling out of the window. Confidentiality rules would have been broken, though. Second chance - larger group and only a mile away, so we had a walk-and-talk debrief instead.
