The co-driver often exercises an important role in strategy, monitoring the state of rivals and in many cases acting as a psychologist, since they also encourage and advise the driver. The rapport between driver and co-driver must therefore be essential and it is common for a driver to change partners throughout their career if they do not feel comfortable. Perhaps for this reason it is very common to find relatives competing. Examples of this are the Panizzi brothers, who raced in France and the world championship, the Vallejo brothers in Spain or the world champion Marcus Grönholm who took his brother-in-law as co-driver during his career.[citation needed]
