Not really - hydrogen shoots straight up into the atmosphere, whereas petrol both pools in the area and also turns to gas and mixes with air quite easily (which is why it's used as a fuel in the first place)
In practice, hydrogen cars are quite safe. They're just not worth the cost in infrastructure and lack of efficiency compared to BEVs.
