The most significant feature is that car remained the main mode of travel afterfor 15 years.
This is very good.... You follow the right structure.... The most obvious observation should come first. :)
The average distance travvelled by car had the most impressive increasing, about 1400 miles per year while individual mode of travel, such as bicycle and walking had a slighly decreasing.

n the other handm colletiv mode, like train and bus, suffered a gently growing i the 15 year-period.
overall, the mais mode in bith years is the car and then the train.

Overall, you follow a very good structure, but too many errors and grammar mistakes.... Also I wish if you expanded the comparison a bit more :)
