When CEOs travel abroad, their entourage often includes a security detail, complete with large men in trench coats and radio earpieces.
Thus, I was somewhat startled to find myself alone on a recent trek across Morocco with Renault Chairman Louis Schweitzer.
We were partners for a drive across the desert, part of an exercise to launch the RX4, a four-wheel-drive version of the Megane. Compared with African trouble spots such as Algeria, Sudan or the Congo, Morocco is a relatively placid nation.
Nevertheless, Schweitzer seemed extraordinarily relaxed on the subject of security, given that one of his predecessors had been assassinated.
The death of his friend Georges Besse clearly affected Schweitzer, but he is not paranoid about his safety. 'It was not a big terrorist plot but the work of a small group of people who killed a number of industrialists at the time,' he said.
Besse was vulnerable. He kept the same routine, had no security and was dropped by his driver at the end of his road at the same time every day. He was an easy target.
'When I first became CEO in 1992, I did have security,' Schweitzer said, as we pounded along the desert track in the shadow of the Atlas Mountains. 'I don't really have security now, only occasionally when I visit particularly high-risk areas.
'Even so, I got told off by Renault colleagues for walking along the beach in Rio during the early hours of the morning when I was suffering jet lag.
'I was also stopped from going on holiday to Guatemala with my family because I was a high risk. There is a lot of kidnapping going on in the country, and I could be a very high-profile target.'
Schweitzer is aware of the need for prudence, but he doesn't wall out the world. And it's a lucky thing - the desert is a beautiful place.
