That being said, the Bentayga can get dirty even if it's just driving on the road, and that's why Bentley implemented one of the coolest headlight washing systems I've ever seen.
Out of the center of the outermost headlight a little arm extends out as if the Bentayga was doing its best impression of R2-D2 or BB-8 from Star Wars. Then the arm squirts out a little bit of cleaning fluid onto the main headlight, washing away any mud, dirt or bugs that may be caked onto it. Seriously, it's a weird little feature and if you weren't aware of it, you'd be a bit startled if someone activated this feature next to you in traffic.
