Omggg how fast is that Hyundai i20 overtaking us going if our car is already going at 120 Kmph?

So as you all know we are going to the hill station Sakleshpura which is about 220 km from our city Bangalore in India in our Maruti Suzuki Baleno and we hired a driver for it so I am in the passenger seat. In my next post I will share videos of our car overtaking multiple cars but in this post I will share this video of our car Baleno going at 120 Kmph and yet that Hyundai i20 is overtaking us so I wonder how fast he is going. I am sure he is driving it at 130+ Kmph. Such speeding is common in Indian highways tho. It's thrilling haha but crazy too that some cars go even faster when 120 is already a lot. Watch the video i shared below of it
