Why? It’s just a fraction of the salary anyway. Like most people only get €0.20 per km since that is what an employer can compensate tax free. With an average one way commute in my country of 20km that’s only €8 a day for a round trip so about €160 a month.
Or a lot of people get a lease car from the company as a perk but then they don’t get compensated for their travel cost.
