A few more remarks about my Inster which also address the comments made above.
So far, I've got no regrets. The flexible internal space is very useful. The sliding rear seats are better for my needs than the Jazz's "magic seats" although smaller dimensions mean there's less capacity than the Jazz. I'm currently getting better than 5 miles/kWh under the same driving conditions which would get better than 70mpg in the Mk 4 Jazz. Winter will be worse but the data at
https://www.naf.no/elbil/elprix-nytt/elprix-vinter-2026 (much colder conditions than I'll never drive in) suggest the Inster suffers a smaller cold weather hit than many EVs. The Inster has flaps under the front bumper which only open to let cooling air in when it's needed (something the Jazz would benefit from having).
There's a volume control for all the safety alert noises and I have that set to be audible but not annoying. The RDMS equivalent is much less intrusive and doesn't get excited when I cross a white line in the middle of the road, perhaps because the infra-red face-tracking camera knows that I'm alive and looking forwards. I've felt a slight turn of the steering wheel when getting close to the edge of the road but it's not an aggressive tug.
I understand that Hyundai issued a software update to address the ICCU problem. The car is extremely cheap to run when charged at home (I'm on Octopus Go) and if I can find chargers away from home that are no more than 50p/kWh then that's no more expensive than petrol at £1.60/litre. I'll miss the excellent range of the Jazz on a full tank but don't reckon on driving more than 200 miles/day. Charging opportunities now feature in journey planning, ideally at places we would visit as breaking in the journey.
