Problem with new players imho is the high level of corruption in certain parts of government and industry. While you cannot usually bribe a policeman in Germany, construction, permitting and industry subsidies and politics are heavily corrupt. Old-school industries are propped up by an old-boys-network and revolving doors between political parties, unions, administration and industry. Many politicians who did well by the coal industry for example got their comfortable retirement position in the boards of energy giants. Same for the car industry. Parts of those industries are even still owned by the state or federal government, e.g. Volkswagen is partially owned by the state of Lower Saxony and Germany.
That is also possibly the reason Tesla is in such trouble over their new factory. While they are a car manufacturer, and a modern, hip and green one at that, which politics openly hails as good, secretly they are damaging established interests by the traditional German car manufacturers and their allies in high positions. So the administration will nod and smile, but try to find ways to hinder them.
