All across Luxembourg there is quite a lot of incentives for using your bicycle but unfortunately not enough parking capabilities. Especially in cities. I suggest that every store (magasin/commerce) that offers parking spaces for CARS over a certain number (say 10 or 20, to cover fast-food, centres commerciaux, etc) has to provide 10% of that number for parking bikes. Parking bikes does not take a lot of room compared to parking cars. So take Belle Etoile, 3000 places de parking - they say they offer 20 places for velos, i never saw them. As per ratio, they should offer 300.
Any fast food has at least 20 to 50 parking spaces, they should offer 2 to 5 for bikes.
