•9hMy running is very low, around 250 km per month, mostly in bumper-to-bumper traffic. I also undertake three to four trips of about 500 km each per year. I am concerned about the future rollout of E30 petrol. In this scenario, should I go for a petrol or a diesel vehicle?

Go for petrol. With 250 km a month in bumper-to-bumper, a modern diesel’s exhaust filter hates short, cold runs and can clog, forcing frequent regeneration and workshop visits. You also won’t recover the higher diesel price and upkeep with such low running, and your handful of 500 km trips a year don’t justify it.
About E30, you can buy a new petrol car which are today E20-ready and the move to higher ethanol blends would be to E30 or even likely a lower blend like E27. An E20 car will most likely not face material compatibility issues as most manufacturers say that they have factored in material compliance at slightly higher ethanol levels given that, that is the case internationally. However, expect a small drop in mileage and performance versus E20 because of ethanol’s lower energy and the fact that your cars ECU has been calibrated with E20 in mind. If you want to avoid ethanol questions entirely, an EV also fits your low daily use and given that most of your driving is in bumper to bumper traffic, an EV would be ideal given its smooth and easy to drive experience. For your 500 kms long trip though, you will need at least one halt to charge.
