EVs are typically 30% heavier (not equivalent mass).
That is a fair assessment now, but how long will that be true for? Two factors are likely to see weight difference reduce and BEVs may even become lighter long term. The first factor is improving energy density as battery technology continues to improve. The second factor is right sized batteries. Currently battery packs are made for a huge range, which is great for road trips and travel flexibility, but there is a large number of cars who's sole purpose is a modest daily commute. As range anxiety is replaced with real world experience the market for cheaper shorter range commuters with small batteries is likely to grow.
When you don't know what you are doing, do it neatly.
