Cars got too wide to fit the parking space.

There is a quiet number that nobody at the design review ever argues about, and it has been winning for twenty years. The average new car in Europe widened from 177.8 cm in 2018 to 180.3 cm by mid-2023 — roughly one centimetre every two years, a creep so slow that no single model launch ever has to defend it. Then you stack the generations. The Land Rover Defender put on 20.6 cm of width in six years. The 2025 Defender now measures almost exactly two metres across the body. Meanwhile the painted bay it has to live in has not moved a millimetre: the standard UK parking space has been 2.4 m by 4.8 m since the 2007 Manual for Streets and the 2010 Building Regulations, and the minimum on-street bay across much of Europe is still 1.8 m wide.

The result is the most ordinary kind of design failure: half of all new cars sold no longer fit the spaces built for them. Transport & Environment found that 52% of the top-100 best-selling cars in the EU in 2023 were too wide for the minimum on-street bay in London, Paris and Rome. Park a 2-metre SUV in a 2.4-metre off-street bay and there is 20 cm of air on each side before you count the car beside you — which is why door-dings, folded mirrors and the contortion of getting a child seat in have become normal, and why drivers' single most-requested infrastructure change is simply wider bays. Cities have stopped waiting. In February 2024 Parisians voted, narrowly, to triple parking charges for heavy cars to 18 euros an hour in the centre — the first European capital to price a vehicle by its footprint rather than its emissions.

Here is the part that should sting a design office: none of this was decided. Width was never the headline of any program. It accumulated as the residue of decisions made for other reasons — a wider track for stance and presence, fatter sills for side-impact and battery protection, broader shoulders for the showroom photograph, a stretched grille to read as "premium" at thirty paces. Each one is individually defensible. Together they produce a car that is objectively worse to live with than its predecessor, and no one in the room ever held the pen on "the car is now too big for the customer's garage." Width is the classic unmanaged drift: a property that every brief borrows from and no brief owns.

The deeper problem is that the showroom and the street optimise for opposite things. Presence is a static, frontal, well-lit quality — it is judged at a motor show and on a configurator. Usability is a dynamic, lived, badly-lit quality — it is judged at 7am against a concrete pillar with a coffee in one hand. Design reviews are staged like the first and graded like the first, so the second never gets a fair hearing until the car is already tooled. By then width is frozen into the body-in-white and there is nothing to do but apologise for it in the owner's manual.

This is exactly the kind of decision that should be stress-tested before the clay, not after the tooling — and it is a decision, not a rendering. The intelligence that matters here is not "make me a wider, more imposing car." It is the ability to ask, at concept phase, what this stance actually costs in the spaces the car will spend its life in: how many of our buyers' real parking bays does this width lock out, how does the door-opening arc behave at the European minimum, what does another 30 mm of presence subtract from everyday usability — and to see those answers rendered convincingly enough to argue about in the room, against the beautiful frontal hero, while the numbers are still soft. Design intelligence is the discipline of putting the unglamorous constraint on the same wall as the glamour shot, early, so the trade is made on purpose. Width creep is what happens when only one of those two pictures ever shows up to the review.

The car will keep getting wider until someone decides, deliberately, that it should not. That decision is a design decision. It deserves to be made by someone who can see the cost.
