Places to use ride on cars with my daughter

[mvallebr]

Hi,

I have a 3 years old daughter and I would like to buy some ride on car for her, like this one -

It's not cheap, but not that expensive and I think it would be a great childhood experience for her.

However, I am struggling to find places where to go with the car. Taking a look at this link - commonslibrary.parliament.uk/science/technology/e-scooters-why-are-they-not-legal-on-uk-roads/ - it seems it's illegal to use the cars on public roads.

I looked at regulations on several parks, like greenwich park, batterseas, and it seems it's forbidden to use mechanical propelled vehicles there as well.

Would anyone know a list of places where these cars can be used in London?

Preferably near Welling, which is where I am moving to next month...
