With a Rs 10 lakh budget, the Tata Tiago EV will be a good option for you. The Tiago EV is a smooth and sensible car, and its small footprint makes it adept for urban usage. 

It gets a 24kWh battery and its real-world range is around 190km, twice as much as your daily usage. However, you will have to charge it almost daily to ensure there is more than sufficient range at all times. By charging the car at your home, the running costs of this EV will be similar to or even lower than those of a bike. 

Alternatively, you could opt for a diesel Tata Altroz. It is a very fuel-efficient option, and even though the running costs will be higher than an EV, these will still be significantly lower than a similarly priced petrol car.

Unfortunately, no EV is available within a budget of Rs 7 lakh. You will have to extend your budget by at least 1-1.50 lakh to purchase the entry-level MG Comet or Tata Tiago EV. 

The MG Comet is an excellent urban runabout, due to its tiny footprint, which makes it easy to manoeuvre and park. Occasionally, it can seat four passengers in relative comfort, with the only limiting factor being access to its rear seats due to its two-door layout. The Tata Tiago EV is relatively more conventional in its approach, and it drives a bit better than the Comet. 

Also, it is the Tata Tiago EV, which will feel a bit more comfortable and confident for the occasional highway drives. Hence, if this is going to be your primary vehicle, we'd recommend the Tata Tiago EV for its well-roundedness.

 If you drive mostly in the city, you can go for the Tata Tiago EV. It fits in your budget, is generously equipped, and is built specifically for the daily city drive. The Long Range version gets a 24kWh battery paired with a 75hp electric motor, with a claimed range of 315km. 

In real-world testing, Autocar India recorded an average range of around 187km, which is adequate for everyday city use, especially if you can charge the car overnight at home. Occasional short intercity trips can also be managed with some basic planning. 

The MG Comet is a good option for a first-time driver. It is easy to drive, has a spacious cabin, despite being a two-door, and the electric powertrain is smooth and silent enough.

However, the 2-doors mean the Comet is not the most practical option in its segment, the boot is small, and the small tyres mean the ride can get choppy. If this is important to you, you could consider the Tata Tiago EV. Otherwise the Comet will do just fine. 

If you are open to an EV and have easy access to charging facilities at home or your place of work, we would suggest you go ahead with one. Your daily running isn't very high, and the Tiago EV should easily manage this on a single charge. 

By opting for the Tata Tiago EV, you will also meet your requirements of low running costs and an automatic gearbox. In fact, with most EVs, the absence of a traditional gearbox means there are no shifts at all, leaving you with a very smooth and relaxed drive feel.

On the other hand, most petrol and diesel automatics at this price segment use an automated manual transmission (AMT), which is not a smooth shifter at all. Thus, the Tiago EV would do you well.
