It may seem overly critical to find fault in a car that's been a joy to drive and I wouldn't hesitate to own if I were doing a job that offered far greater financial rewards than what I receive for typing these words, but when an exec model arrives from a brand with a luxury line, a part of me, perhaps unfairly, expects perfection.

First up, while the Jaguar XF Sportbrake's blind-spot monitoring system has been great, the yellow warning icons that appear in both side mirrors have occasionally failed to deactivate after, say, a motorbike has passed and is replaced by the railings that divide a dual-carriageway or keep pedestrians apart from the traffic, although I am speculating that it is the railings that are fooling the radar technology into staying on.
