I have found a better bus company, from Poland, named Solaris.

Solaris website: https://www.solarisbus.com/

Why is it better?

1. They have full electric busses.

2. They have great battery life (vehicles will be fitted with 6 batteries with a total capacity of over 470 kWh). 

3. They're very spacious.

4. Automated systems of assistance for the driver, including the features MirrorEye or MobilEye Shield+.

5. Made in the European Union, so the price will be without VAT

6. They can be bought by European Funds
